Cups, empty ice cream tubs, measuring cups, Barbie dolls and bubbles! LOL

The few occasions I have bought "bath toys" (which are, as an aside, ridiculously expensive!) they are been popular for all of 35 seconds before being passed over for the tried and true amusements from The Tupperware Cupboard!

Oh, and very popular to play with the sponge shapes - I buy packs of super cheap Homebrand dish sponges, and cut them into shapes. They stick to the side of the bath, float and the girls love them.
