ifluff for itouch?
 

ok i love this game (ifluff friends for ipod touch). its so cute. but i have a question.how do you unlock more animals/fluff? i bought all of the habitats and all of the decorations, but i got nothing. i did unlock the penguin after getting 1500 munnies.
how to get them would be greatly apriciated. especially on howto get each idividual one.
any advice for it is awesome.
