He was just a pup when Pollito was chased out by his pack leader alongside Chato. The latter saving him and dragging him by the scruff whenever he was too tired to keep moving. Though he may be too prideful to admit it he truly is grateful that Chato took care of him. When they first arrived in Jagged Rock he was very intimidated by the original three. His outgoing personality quickly overruled that and he took quite the shine to Malvado. Being the baby of the two Pollito was given a much kinder pupname. His brother likes to joke his name is the reason his ego's so big.
While he is prideful, Pollito is strong and excitable. He is a bit of a troublemaker, though mostly because he's had a new level of freedom since he joined. Malvaldo is usually the one to reign him in, as the pup looks up to him. He enjoys the stories the travelling wolves bring whenever they stay though he is quite content on staying with the pack.
