PetVille limited edition Valentine's gifts -- Day 1: Pet Lisa painting

For those who want to say "I care" to fellow players, PetVille's unleashing a new series of limited edition giftables in honor of Valentine's Day.

For one day only, the Pet Lisa Painting can be sent to friends who would surely be honored to hang such a masterpiece in their pet's pads. Also, if you give, you're more likely to receive, and if you collect them all -- you'll "win special prizes" for your pet.

There's no other hints to what those prizes will be, but even so, how can we possibly resist the Pokemon-like command to "catch 'em all?"
