Best friends Jess and Lily love all animals. But when they follow a mysterious golden cat into Friendship Forest - a place where animals live in tiny cottages and sip dandelion tea at the Toadstool Cafe - their summer holidays suddenly become much more magical. Goldie has invited Lily, Jess and kitten Bella Tabbypaw for a sleepover. The girls can't wait to spend a night in Friendship Forest, but brave little Bella decides to go exploring on her own - with the Boggits. Lily and Jess must head into the tunnels underneath the forest to find her, but will Grizelda the witch get there first?
