This restaurant looks fun, but be warned - the bills are huge.

Toucans are having a great time at Leeds Castle near Maidstone thanks to the efforts of an ingenious keeper who invented a fun lunchtime game.

Mairee Vincent designed this version of the children's game Kerplunk to help enrich the lives of the castle's colourful and rare Toco Toucans.

In the game, a canister has many coloured straws stuck through it and several marbles balanced on the top.

The aim is to remove the straws without dropping the marbles.

The birds have to work out how to remove chopsticks from a suspended tube in order to release fruit contained inside.

But it's not just good for the birds - Toucan Kerplunk has won praise for Mairee too having been voted Best Environmental Enrichment Device by animal experts at The Regional Environmental Enrichment Conference (REEC) in May.
