The quick answer

Realistic sea creatures are gold for small-world play. They end up in the bath, the sandpit, lined up on the windowsill and in all sorts of rescue games. Here's what we'd buy.

Questions parents ask

What is small-world play?

Playing out stories with little figures: rescues, families, adventures. It's brilliant for talking and imagination, and sea creatures work anywhere, from the bath to the sandpit.

Are these OK with younger siblings around?

Check the age on the box. The Playmobil set has lots of small parts.

How do I make a cheap rock pool for sea animal toys?

A shallow tray, blue water and a few pebbles. Put a towel down first.
