Do so at any time to unlock Cliché # 01/01 (Double Jump) There is one 'Cliché', a kind of collectible, awarded for performing (in the case of this stage here) about 10 double jumps. Start by following the white bunny across the town, past a few jumping platforms (jumpers) Trophy: Choco Duff Dark (5 Duff Bottlecaps) Cliché: Double Jump (perform a total of 10 double jumps)
Just out of curiosity, the achievement is unlocked even if you press A to play instead of Start.
