For St. Patrick's Day.

Ever notice how Blossom and Bubbles don't wear green? Now you know Buttercup's going to take advantage of that.
Oh well, at leas the Gangreen gang are safe from her pinchers for once.

Buttercup: It's pinching time!
Bubbles: Oh no! Blossom, we're not wearing green!
Blossom: Don't worry Buttercup won't pinch us if she knows what's good for her.

Ace: Relax it's St. Patricks Day.
Snake: We won't get pinched for St. Patty's day!
Little Arturo: Si. We're green!
Big Billy: Duh, Billy like hamburger patties!
