This is a game for toddlers so I seriously hope you do not struggle to get this
From the main menu choose Big PooYoo
learning level and then select Workshop
and choose the 'Sky
Once the game begins you will be told what do to, the PooYoos have jumped through the cloud in the middle of the screen and its your job to identify who it was between the two PooYoos on screen.
This is very simple to tell but ill give you tips on how to tell who jumped through the cloud:Rabbit - Long ears
Elephant - Wide ears on head/Trunk on left of head
Cat - Long tail/Pointy ears
Pig - Stubby ears/Curly tail
for the left PooYoo and
for the right PooYoo.
Do this correctly 15 times (5 times per 'round') and the trophy is yours.
