Malarko Editions has made these three-color screen printed kids t-shirts with a walking poo on them in "super limited edition." Because if there's one thing you don't want to see walking toward you on the street, it's a poo.
Shirts will fit kids from ages 1-8yo, as long as 1-2yos wear the 3-4y size like a dress or large poo tunic, or as they say in England, a poonic.
Walking Poo Kids Tee, £19.00 + shipping, &c. [malarkoeditions via anorak]
