00:00Bobby arrives at the station to pay a visit to his grandmother.
00:03The train takes 3 seconds to enter a tunnel that measures 1 km long.
00:08If it travels at a speed of 120 km per hour,
00:11how long will it take to cross this tunnel?
00:24120 km per hour means 2 km per minute.
00:28It will therefore take 30 seconds for the train to travel 1 km,
00:313 seconds more to enter the tunnel,
00:34which makes a total of 33 seconds.
00:399 years ago, Bobby was 9 years old.
00:42How old will he be in 9 years?
00:53If Bobby was 9 years old 9 years ago,
00:56it means that he is currently 18 years old.
00:59Thus, in 9 years, he will be 27 years old.
01:05In the train, Bobby is hungry and takes out some snacks from his bag.
01:09He has a chocolate bar made up of 2 rows of 8 squares each.
01:13He can break this bar vertically or horizontally,
01:16but he would like to break it so that each square is separated.
01:20How many times does he have to break the bar to get there?
01:26How many times does he have to break the bar to get there?
01:342 times 8 is 16.
01:36So, if we separate each piece of chocolate,
01:39we will get a total of 16 pieces.
01:42Thus, you will have to break the bar 15 times.
01:47Bobby arrives in the village.
01:49He walks to his grandmother's house.
01:51Suddenly, he notices that his neighbor has a new very aggressive dog.
01:56But the chain is long enough for the dog to reach the door of his grandmother's house.
02:00How can Bobby reach the door?
02:11Bobby should run in circles around the tree.
02:14The dog will chase him and will end up rolling around the tree.
02:17After that, the door will be out of reach of the dog.
02:22Bobby enters the grandmother's house.
02:24Can you spot three mistakes in this image?
02:35The woman in this portrait has lost a shoe.
02:38The sun can not go down at noon.
02:40And grandma has a rat hidden in her wool ball.
02:46Grandma shows Bobby her new parakeet.
02:48Can you find his number?
02:55Only the fourth shadow is correct.
02:58Grandma asks Bobby to repaint her living room.
03:01Can you find five words in the freshly repainted room?
03:13The first word is bui.
03:15Here is the word pot.
03:17The third word is ibou.
03:19And it is hidden here.
03:21The fourth word is sow.
03:23And the fifth word, broom, is right here.
03:28Bobby hears the bell ringing again.
03:30He opens the door and sees three grandmothers with sweets.
03:33These ladies are neighbors who came for tea.
03:35But one of them is not really human.
03:38Can you guess which one?
03:41It is the first old lady who is the intruder.
03:43Look closer.
03:44She has three hands.
03:47Grandma invites her friends, Thelma and Violette,
03:50to have tea with Bobby.
03:52He leaves the table for a few minutes, then comes back.
03:55He takes a sip of tea and realizes
03:57that someone has added pepper to his drink.
04:00He takes a sip of tea and realizes
04:02that someone has added pepper to his drink.
04:05He takes a sip of tea and realizes
04:07that someone has added pepper to his drink.
04:10He questions the old ladies.
04:12Grandma answers,
04:13I was cutting the cake in the kitchen.
04:15Violette declares,
04:17I was watching TV in the living room all this time.
04:20And Thelma retorts,
04:22I was taking pictures of the cat in the hallway.
04:24Who is lying?
04:26It's Violette.
04:27There is no TV in the living room.
04:32Grandma's cat is hiding somewhere in the house.
04:35Can you help Bobby catch it?
04:47The cat is in this locker.
04:51The cat is in this locker.
04:53The cat is in this locker.
04:57Later in the day,
04:58Grandma asks Bobby to help her
05:00put fruits and vegetables in cans.
05:02Finally, she feels tired and goes to bed.
05:05Bobby promises to finish everything on his own.
05:07Oh no, he lost the recipe.
05:10Bobby only remembers that there should be
05:12an odd number of identical ingredients.
05:141, 3, 5 and so on.
05:17What ingredient has nothing to do here?
05:23What ingredient has nothing to do here?
05:29It's Lyle.
05:31What do you think of this set of ingredients?
05:33Can you spot the intruder?
05:43There are 6 cherries.
05:44Bye.
05:47What do you think of these fruits?
05:53What do you think of these fruits?
05:58The apricots don't belong here.
06:02Bobby doesn't have any more cans.
06:03He goes to the barn to look for more.
06:06Unfortunately, Grandma has put a combination lock
06:08on the door of the barn.
06:10Bobby looks around him and finds a note with a clue.
06:13Can you help him decipher the code?
06:23This code is not so simple.
06:25You have to count the number of boards on each wall.
06:28And the password is 7954.
06:34Bobby helps Grandma organize boxes in the barn.
06:37Can you spot which box has the largest number of boxes inside?
06:50It's the first one.
06:53Bobby tries to organize Grandma's teapots.
06:56Can you guess which teapot contains the most?
07:07It's this teapot.
07:11And now, Bobby's task is to locate the smallest skin cell.
07:15Can you help him?
07:24It's the third skin cell.
07:28Bobby's Grandma knows a little bit about magic.
07:31She gives him the task of marking these 6 bottles filled with potions.
07:34Can you help him?
07:44It's quite simple.
07:45The bottles contain a few clues.
07:48The first one is filled with tooth whitening syrup
07:51and the second one with frog broth.
07:53The third bottle is filled with tonifying tea
07:56and the fourth one contains an eternal love potion.
07:59The fifth bottle is filled with infinite wealth
08:02and the sixth one contains a freezing fluid.
08:07It turns out that Bobby's Grandma has a dragon egg in her barn.
08:11It is very rare and very expensive.
08:13That's why she hid it among the factitious eggs.
08:16One of these 7 eggs is not wrong.
08:18Grandma asks Bobby to find it.
08:20Here is a clue.
08:22It should have a little pink color
08:24and there is no bubble on its shell.
08:26In addition, the egg is not in the middle
08:29and it is not next to the blue egg.
08:31Where is the dragon egg?
08:41Only this one really matches the description.
08:45Bobby leaves the dragon egg in the living room near the fireplace
08:48to keep it warm.
08:50Finally, he goes to bed.
08:52The next morning, he discovers that the egg has hatched.
08:55Can you help Bobby find the little dragon?
09:06It's here on the shelf.
09:09Suddenly, the doorbell rings.
09:11Bobby opens the door and sees two gardeners.
09:14One of them is an imposter from another planet.
09:17Can you guess which one?
09:27It's the man on the left. He has no ears.
09:32Bobby asks the imposter to leave.
09:35But instead, he violently pushes Bobby away,
09:38runs into the house and steals the little dragon.
09:40The thief escapes towards the forest.
09:42Bobby chases him.
09:44He falls on these three roads.
09:46There is a family of bears that roams on the first road.
09:49The second path has been bewitched by an evil wizard.
09:52Any animal or bird that dares to take this road
09:54turns into stone.
09:56And the third road is infested with pathogenic ticks.
09:59Which of these roads seems the safest?
10:11The second road is the right one.
10:13The spell only works on animals and birds.
10:16Not on people.
10:18Bobby finds the thief's spaceship in a field.
10:21He sees the dragon in a cage nearby.
10:24Can you help Bobby decipher the four-digit code
10:27to unlock this cage?
10:37This note nearby is a clue.
10:39Earth is the third planet from the sun.
10:42Mercury is the first.
10:44Mars is the fourth.
10:45And Venus is the second.
10:47The code is therefore 3142.
10:51Bobby saves the dragon and brings it back to his grandmother.
10:54He decides to go home by car.
10:57The whole trip will be 100 km.
10:59First, he travels 30 km to a gas station
11:03and refuels.
11:04Then, he drives 15 km more
11:07until he reaches a car wash station.
11:10After that, Bobby drives another 20 km
11:13and takes a break near a small hotel.
11:15It is at this moment that he realizes
11:17that he has already used exactly half of his gas tank.
11:20What do you think he should do?
11:22Keep driving to his house
11:24or go back to the gas station?
11:26How long does it take to reach Bobby's house?
11:34It takes exactly 35 km
11:36to reach Bobby's house.
11:38And if we count how many kilometers
11:40Bobby has traveled since the gas station,
11:42it also gives us 35.
11:44This means that Bobby's gas tank
11:46will run out at the exact moment
11:48he arrives at his house.
11:49He should therefore absolutely not return
11:51to the gas station.
