- Who's Calling Me Now? is the 12th episode of the second season of Pocoyo.
Pocoyo discovers a box with a group of whistles and discovers a whistle that calls Pato. Pocoyo then blows it multiple times. Eventually, Pato gets angry, discovers that same box, and blows a pink whistle. That one turns out to call Elly, much to her annoyance. She then blows a brown whistle that brings over a confused Loula. Loula then finds a blue whistle that calls Pocoyo. Pocoyo then blows his yellow whistle, and Pato, confused, looks for the one who called him. Pato gets mad and blows the pink whistle and calls Elly. Elly then calls Loula, Loula calls Pocoyo, and Pocoyo calls Pato. Soon, this situation becomes an angry fight. Baby Bird then flies by, but is knocked away by all the noise. He then cries, and Pocoyo, Pato, and Elly realize the error of their ways and stop using the whistles. Baby Bird then finds a green whistle, and that one blows up a dance party.
