Hide and seek birthday treat

Leopard wakes up with a fluttery tummy. "It's my birthday!" he shouts with glee. "I'm awfully excited, my friends are invited to a yummy big birthday tea!" But when Leopard sets out with his invitation, he finds there is no one there for him to invite. Will Leopard have to celebrate his party all alone? Go round the jungle with Leopard and see if you can find his friends hidden on each page.
