When Carlos drops his umbrella to climb a tree for a better view of the animals, they all cram into the banana-leaf umbrella as it floats by -- from the little tree frog to the baby tapir to the big jaguar and more. It gets so crowded in the umbrella that there isn't even enough room for a little hummingbird! So over the umbrella tumbles, everyone falls out, and poor Carlos comes back wondering why he didn't see any animals all day.
