Wally The Watermelon
Wally the watermelon is both a bath toy and a natural teether, made from wild rubber from Hevea trees. They're made from one piece with no holes so water won't come inside.
They are hand painted with food grade dyes, so they're completely safe for your little one to chew on.
To clean, simply wipe with a damp cloth and soapy water. No not sterilize.
