Nico the Toad is always a bit grumpy. But recently he's been grumpier than ever. Stella the Mouse, Delilah the Spider and Bo the Parakeet think the school trip to the art museum will cheer him up.

But the animal friends have never left the school before.

If they stick together nothing can go wrong, can it?

Friendship takes centre stage in this early chapter book from the Classroom Critters series.
