Hidden rabbit mug:  $3.44 @ Superstore (RSP:  $7)

I've seen these for a while, but I don't like paying more than $3 for a mug.  They're so much more online though!  I've seen similar ones go for $20 plus, so these seem worth it even at full retail.  They are pretty big and nice.

Squirrel - would have been my second choice:

Fox - I liked this one the least.  It doesn't have a face!

Owl - this one was alright:

I might pick up the rest if they go cheap enough, but I kind of doubt it.  They've been the same price for over a year now!  Stock is almost gone, so it seems unlikely.
