What’s has four legs, is colorful and shiny, and helps raise money for a good cause?

Why, a Tzedakapotamus, of course!

It’s a nine inch long tzedakah box labeled with two slogans, “hippos for justices!” and “three cheers for giving!”

The Tzedakapotamus is the creation of Lisa Pierce, a Maine artist who sells them at her online store, etsy.com/shop/thevanillastudio. Ms. Pierce has taken nondescript hollow plastic toys, cut a hole in their backs, painted them, added a stopper, and voila! A beautiful charity box.

“Why a hippopotamus?” we asked.

“Why not hippos?,” Ms. Pierce replied.
