Peg Mooring is one of the members of Clutch Powers' Brick-Building Team. She is calm, relaxed, kind-hearted, but sometimes can be bossy. She is also very intelligent and knows a lot of things to specific detail. She also finds an interest in Clutch. She is noted for discovering thirteen different species of aquatic life. Shortly after being introduced to the team, Bernie came flying into the room they were in, making his hairpiece fall off. She came to his aid, and immediately he developed a crush on her.
