Sir Crustworthy is a plant NPC in Plants vs. Zombies: Battle for Neighborville that only appears in the Food Fight festival. He resembles an Acorn wearing a green "Tasty Topper" hat. He gives you the pie scavenger hunt quest, which can be completed by collecting 24 pies scattered across different maps. Completing the Pie scavenger hunt rewards the player with the "Tasty Topper" hat for the Acorn.
His name is a portmanteau of "crust," the shell of a pie, and "trustworthy."
