After getting sent back in time that took place where Dinosaurs were there, Leo walked around while you, Donnie, Raph, and Mikey just stood there, looking around in awe

Mikey: This is cool, yo

Donnie: Look at the T-Rex

Just as Raph was about to comment, you all heard screaming. You look over and saw Leo on a triceratops' back, struggling. You, Raph, Donnie, and Mikey were all holding back laughter. Raph loved watching Leo be miserable

Leo: STOP, TRICERATOPS, STOP

He screams, but the triceratops kept running around, not listening to Leo
