A set done called "Swwet puppie"by Paula Baez, posted on clipartoon on August 31.
Later, on september 6 appears "little puppy" at clipartopolis:
Same kind of puppy, taking the same bath, taking the same posses, actions, Tail, etc.
As if someone says: Hey! Take The clipartoon set an do something similar! Just copy the way it's done.
This way is so east to do sets. Feeding from us.
