Rinkus was tired of flying around aimlessly. He was getting restless, and when he saw Pterano flying with Devon (wasn't that Sierra's son?) and that small gnat that he'd swatted into the lake, his rage bubbled up within him. "Ooooh that Pterano! He'll get what's coming to him, if I have anything to say about it, I think." he muttered. He began following, but at a distance. As Pterano, Devon and Petrie drew closer to the gang, Rinkus's eyes lit up. Finally! Some action! Rinkus was losing his patience, and he no longer wished to skulk around. He wasn't sure what he'd do, but seeing Pterano there had sent him into turning plots over in his mind.
As Pterano was coming closer, Littlefoot brightened up at Chomper's suggestion. "Yeah! Let's play something!" he said, excitement growing in him now.
Pterano could see the gang, and he smiled as he prepared to land. He was a bit perturbed at seeing Cera, but he knew she would just have to deal with his presence now, guilty as he felt about it. "Well hello children!" he exclaimed, rather grandiosely as he was prone to doing.
Spreading a wing out with a "whoosh" as he landed, he looked about him. "I have brought Petrie here to share in the fun, excitement and games that I'm sure you children have been getting in to recently." he said, not suspecting what they had really been discussing.
As Pterano spoke, odd gray clouds began gathering in the sky, though they seemed to be coming from every which direction at once, and converging on the Great Valley. They were rolling in, a noise like distant thunder beginning to sound.
"Mmmph." Littlefoot said, noticing. "That's not good. We can't play if skywater is gong to fall." he said, lowering his head in a dejected fashion. It was at that moment that the Rainbow Faces pattered up.
"Children!" the male said, a concerned look on his face. "Where are your parents? They should know that a..." but before he could finish speaking, a certain pink streak swooped down from the sky, nabbing Ducky in its foot.
"Gotcha!" Rinkus exclaimed, cackling as he began beating his wings to fly off. Pterano gasped, recognizing the assailant at once.
"Rinkus!" he cried, shock written upon his features. "Let her go! NOW!" he called, but the pink rhamphorhynchus paid him no heed as he began to make off with the swimmer, still cackling as he noticed the gathering clouds. A storm... perfect! He could use it to elude Pterano, and make clear out of the valley.
"RINKUS!" Pterano shouted, and took to the sky after him. "Come back! Let her go!"
"Guys! Come on!" Littlefoot urged, and took off after Pterano and Rinkus. He wasn't going to simply abandon Ducky like that, and he doubted any of his friends would either. Hyp shook his head, and began following after Littlefoot, muttering about who he wasn't sure was the bigger idiot, Littlefoot for chasing or himself for following.
"This isn't good." the male Rainbow Face stated, watching the unfolding scene with apprehension.
"Come on, we can't just leave them when it's about to happen." the female stated, and the male nodded solemnly, beginning to join in the odd chase as well with his companion.
