The Trio

The Trio is the group name of an elite pig squad. The group consists of Iggy, Piggy, and Zach. They appear every 3 worlds in Angry Birds: Bubbles.

Iggy
Iggy is the first member and is the least intelligent. He is extremely unaware of what he's doing and acts crazy, although he does seem to know the difference between a bird and a pig. Iggy is not a fierce adversary as he just drops wood to construct structures to block your path. His structures can be easily bypassed or destroyed, allowing you to easily defeat him.

Piggy
"Not to be confused with Piggy (Yoshifan1219)." Piggy is the next member and is the brains of the group. He is very intelligent and knows how to build and heal pigs, but knows little of how to battle, so he is an easy fight. His attack is to fire pigs at the birds to stop them, as well to build. This may seem difficult, but because of the random placement of buildings and the slow firing rate of the cannon, he is an easy boss.

Zach
Zach is the final boss of the trio and is the captain and the brawn of the group. He is of average intelligence and knows mainly how to build and to take care of birds. He is the most difficult boss by far, he fires at birds and builds structures similar to the other two bosses, but can spawn in pigs to block the player. The cannon is much faster than in the previous fight, and the buildings are placed better. He is a much harder boss than the others.

Personalities
Iggy is the dumbest member of the group. Although he seems crazy at first, he understands what he is doing and why. He is very funny to other Pigs and is liked among the Pigs. He doesn't like the Birds at all and usually refers to them as terrorists. He is friends with Daisy and they have been since childhood.

Piggy is the smartest and oldest of the group, although Zach treats him like he's younger, which annoys Piggy. Piggy was responsible for the Decipiger but was told by his superiors that King Smoothcheeks wanted the destruction of Bird Island. Piggy raised Iggy and promised to protect him, which leads Piggy to be a little overprotective at times.

Zach is the strongest and toughest member of the Trio. Zach was born around the same time as Iggy. Zach was found in an onion basket in a small Pig village. Zach was adopted by the General of the Piggy Army after showing signs of physical strength. Zach was trained every day to be a soldier, although he really did not want to do it. Zach joined the army after the events of The Angry Birds Movie.
