Rex the T-Rex towered over his classmates, his massive tail swaying with excitement. Tina the Triceratops chatted eagerly with Barry the Brachiosaurus, their voices mingling with the chorus of chirping birds. "I can't believe we're finally learning manners today!"

"Class, settle down! We can't learn about etiquette if you're all behaving like wild dinos!" "But Professor Pterry, it's hard to stay calm when you're as huge as Barry!"

"Rule number one: No roaring during mealtimes," he explained, pointing to a carving of a T-Rex with a big 'X' over its open mouth. "I guess that means no more food fights," Rex chuckled, earning a giggle from Tina.

"Please pass the leaves, Tina," Barry said, extending his long neck gracefully. "Here you go, and thank you!" Tina replied with a smile.

"Watch out for that slippery moss!" Rex warned as he steadied Tina with his tail. "Remember, manners even in a storm!" Professor Pterry called out, soaring above the commotion.

"That was a wild lesson, but I think we did well," Tina said, shaking water from her frill. "We might just be the best-mannered dinosaurs in the jungle!" Rex declared proudly, and the classmates cheered in agreement.
