Toy turtle that swims underwater

[Notanotherone5]

Hi

My son wants a toy turtle that swims by itself underwater for Xmas. I can only seem to find ones that float on the surface (like the lil love pets ones). Does anyone know of one that meets the brief? Thanks

Bump for the night crowd….

We have a little live pets one that has been great. Button to turn on and off, crawls on ground and swims in water, although mostly on the surface.

I saw toys like this in Hamleys. Definitely a shark.. maybe a turtle. Quite small. About 15 quid.
