Yep I chuck them out ever 6 - 12 months and buy new ones as its feral!!!

We have ducks, whales, star fish, frogs etc etc lots that squirt!!!

Plus cups with all diff shapes holes in the and wind up toys too.

I have found that since i got a hangy heshen bag thing they dont get as bad mould as fast.
Yep I am with Feeb. We also have ones that don't have any holes in them, so water doesn't gather and they play imaginary games with them. Think I got them from Scienceworks..DD loves playing with soar soars (dinosaurs) and the sharks! I think the brand is wild republic? Not technically bath toys, still do the trick They also take their cars in too.
