Poached Eggs 2-21 is one of the first levels the Foreman Pig appears. This is also the first level with a Foreman Pig boss, known as Mr. Moustache.
Shoot Matilda's Egg at the leftmost Corporal Pig. Use Red and Chuck to thin out the wall to the left of the next pig. Use Chuck to destroy the floor underneath the next two Corporal Pigs, which will kill not only them but the Foreman Pig underneath it as well. Finally, use Bomb to finish off the last Corporal Pig. Matilda awards the player 10,000 extra points if she's unused.
