Who here hates the word M**st? Everyone does, right?! So you can imagine what this did to Peter's self-esteem growing up. All the bullies in school taunt him, "Peter, the M**sture Metre". It's a touchy subject, so now he goes by Peter, just Peter. But trust us, he's still pretty stellar at telling you when your green amigo's soil is m**st or too dry. Just give Peter a chance and be his soil mate will you?
