For dandloyd1966 : as squiggly2014 said, get the pegs in the order in which the top animal eats what's bellow it...
For PoisonValek : move to the edge of the cliff and click the squirrel.
For Dukf2 : actually, there is Virozui3072's comment, from may 10th. It really helped me when i got stuck.
For kwolf18 : you need to be careful about the ORDER of the colours... :-B

AXEL4520 : the ending was explained more than once.
