Rabbit Hops (Bunny Hop in the UK version) is a puzzle in Professor Layton and the Unwound Future. The puzzle must be solved in order to progress the story.
Puzzle
- US Version
This peculiar rabbit has a unique method of getting around.
He travels 70 centimeters with each hop, but when he lands, he immediately hops 30 centimeters toward the direction his tail is pointing.
On a straight line, what is the minimum number of hops it will take this rabbit to reach a spot 10 meters away?
- UK Version
An uncommonly clever rabbit has imposed some rather strange rules upon its movement. It can jump 70 cm forwards, but after every jump forwards, it must jump 30 cm in the direction of its tail.
If this rabbit needed to travel 10 m in a straight line, what is the lowest number of jumps in which it could cover the distance?

Too bad!
This bunny is kind of weird, but he's also quite clever.
- UK Version
Bad luck!
The rabbit is certainly eccentric, but there is no doubt it is clever.
Correct
- US Version
Hop, hop, hooray!
Twenty hops is correct.
If the bunny rabbit turns 180 degrees in midair during each 70-centimeter hop, he will land and then hop 30 centimeters toward his tail, which will be pointing forward toward the target spot.
Using this method, it will simply take the bunny two hops to cover each meter!
- UK Version
That's right!
The answer is 20 jumps.
After every 70cm jumps forwards, the puzzle rabbit turns around 180 degrees and jumps a further 30 cm in the direction of its tail, thereby covering 1 m in two jumps.
