Small Pigs are pigs featured in the first four Angry Birds Games and are the smallest of the entire Pig. It is the first pig encountered in the entire game, starting at Theme 1-1. It is also the weakest pig in the games it appears in, and is defeated by a simple falling bird or block. It is weaker than all the other pigs in the game and is very common after its first appearance.
Small Pigs, like the other pigs, will be able to roll but will unlikely be pushed and will likely be popped even through the slightest tap. Their injured sprites can rarely be seen due to their easy defeat.
Medium Pigs are medium sized pigs and the 2nd weakest pig in the game. Because of its medium size, it is the second largest of the Minion Pigs. It can be easily destroyed by all birds, but usually in large buildings.
It is weaker than the Large Pig, Corporal Pig, Moustache Pig and King Pig. The only pig that is weaker than this pig is the Small Pig. It first appears in Poached Eggs Theme 1-14 and is quite common after its first appearance.
The Medium Pigs are the most used pigs in the series, and are typically the only sized pigs seen in most animation series.
Large Pigs are large sized pigs in the Angry Birds series and is the largest of the Minion Pigs. This pig is the third weakest of all the Pigs in the game, and is weaker than the Corporal Pig, Moustache Pig, and King Pig, and is stronger than the Small Pig and the Medium Pig.
