Make a creative poster for me in photo format. Dimensions are 42 x 59.4 cm in portrait. The title should be "Be a Dyno-mite, Not a Dyno-mean . Let's make ragging extinct. "Put dinosaurs in the poster. There is a devil looking t-rex, red colored, with short arms, that is bullying three baby dinosaurs. The t-rex is looking shocked and embarrassed. There is a green dinosaur wearing a baseball cap, smiling, with a text bubble that says, "don't be a sore lizard, use your head, not your arms". A blue colored baby dinosaur, wearing sunglasses and has a starbucks cup in his hand, standing beside the green dinosaur, says, "yeah bro, it even gives you plus aura points". Make the whole thing very cute.
