I refuse to believe these have any practical use. The only explanation is that this Etsy shop is where turtle superheroes get all their outfits. Supervillains, maybe, but I’ve never heard of a turtle supervillain before. Turtles can’t be evil, can they?
(they’re so you can see your turtle when they wander away in your lawn. Don’t worry, it’s a turtle, you still have several days to catch up with them before they’re out of eyeshot. )
