I have so many snapdragons around I didn't manage to potty train my latest toddler. His bladder was just never full.
Use evil jack-in-the-boxes on them if they're not below 3.5 grouchy. That will make them want to pee again.
Heheh. We need someone to make a mod so that when the evil Jack-in-the-Boxes go off a miniature Pescado pops out. Of course, that may simply cause them to vent their bowels there and then.
