When Hector's friends don't show much interest in his new dance, he huffs off to the huff tuffet. Once there he spots a potential new friend - a small rock! Hector names him Colin and decides to keep him as a pet. The friends love Colin and quickly decide to find their own pets - a stick, a feather, an apple, a sunflower - but it's all getting rather competitive. Can the Little Yellow House's first ever bring-a-pet party save the day?
