I thought the other one was polarbear and lion. Unless my eyes are deceiving me, that's a squirrel and a lion. Haha. Good job though. I like the polar bear and lion one the best so far.
Hmmm... Now this one's just plain creepy. The previous one was adorable, but a squion in the high grass - that gives me goosebumps: what if I won't see it until it's too late?! :)
