Guillermo's Iguana

Guillermo's Iguana is a blue lizard that appears in The Secret Life of Pets.

Bio
Pops agrees to help find Max, so he moves by various ways, including a big flock of pigeons. He and the other pets arrive in the balcony of Guillermo's Apartment, and Pops knocks the ceiling window; the iguana opens the window with its long tongue, so the pets enter the apartment easily and all the food on the table of the owner, is gone.

Trivia

 * Though Guillermo is seen as a pet babysitter, it can be assumed that he owns the iguana.
