Follow the dog.

Exploration Stage: Yard of Forgotten Toys
From: Adeline Svensson
Description: To save the city from flooding, I should find a mating animal. ...... There's a silhouette of an animal on the treasure chest that's hard to decipher. If you use your imagination and look closely, it looks like a dog. I must return it to Martha before the water ruins my newspaper! Let's find the dog.
Completed: What a cute dog! Nice work. With Martha, the animals have been returned to the ancient figurines of Noah's time. Looks like their place is in the treasure chest.
