Maybe a stupid question

Hi all,
i would like to embedd an ai to my blog, based on pandorabots.
But it should get a real personality, so I want to let it look as a sheep.
is there any affordable software for creating a sheep?

Help would be apreciated.
(And sry for my english, I am no native speaker and a little bit out of pracrice).
Best regards,
Voodooschaaf
