You can also use the moulds to make jelly bricks. The jelly pops out really easily and makes a tempting party dessert.

4. Lego Ninja Pinata, £14.99


If your child LOVED the LEGO movie, or has a real soft spot for the LEGO Ninjago characters in particular, they'll love these pinatas, which come in a choice of white, black, red or green.

Note the pinata comes empty so you'll need to fill it with your own choice of sweet treats, and a stick isn't provided - though hopefully you'll have something suitable to use at home.

(Do make sure there's an adult around when the kids are playing this game!)

10. Building Block Pull-string Pinata, £9.49


If you like the idea of a pinata, but there will be younger children so you're not too keen on one you bash, why not get a pull-string pinata instead?

Each child takes it in turns to pull a string, and one magic thread opens it up. Once again, the pinata is empty, so you'll need to fill it with goodies.
