Greeny's name comes from his skin and beard color.
He is shorter than Big Dave but slightly taller than Lucky. Like Big Dave, he also has a shamrock tattoo on his forearm, but on his right arm. He wear typical green clothes and has an eyepatch on his right eye.
Like Big Dave and Lucky, he has a green motorcycle that shoots rainbows out of its exhaust pipe. Later, he helped Big Dave and Lucky break logs of wood for firewood to boil Timmy, Cosmo, Wanda and Poof. After being turned to ash by the Great Potato, he explained that the McPunchies just wanted the pot that used to contain the gold because it was a family heirloom.
