Gi-Go Drink n’ Wet Baby

These are modeled after the G1 Drink n’ Wet baby ponies. They can be combined with a Fancy Pants-style painted diaper, or regular symbol.

This one appears to be by another manufacturer. It is slightly smaller and the plastic is  squishier. They may or may not have painted diapers and/or hooves. They are sometimes marked by Toysmith.
