Big Dave is a "lepre-convict" who was put away for what he did to the last person who stole his gold. He is much bigger and stronger than his brothers, Lucky and Greeny.
Description[]
He is big, strong, and has a black beard. His pupils are colored red. He also has a shamrock tattoo on his forearm.
Background[]
He and his family escaped from prison to find Cosmo, who left them a letter telling them he "tuk yer gold". When Cosmo tells him Mr. Crocker has it, he says that they need to get it back before the end of Leprechanuka, or else. As hard as Crocker, Timmy and Cosmo tried, they couldn't get the gold, so Dave took them to Ireland. He attempted to boil Cosmo and his family and vaporize Crocker, but his family couldn't find the vaporizer and people couldn't be boiled on Leprechanuka. Timmy apologizes for taking the gold but it turns out Dave and his brothers just wanted the pot back, as it is a family heirloom, so Mr. Crocker unwillingly gave him the pot and they ended in good terms.
