Well... If it was really Regan's order. Rapier wasn't too pleased about taking an order from someone else, but he understood the situation well enough to know better than to argue right now, too. He motioned with his head toward a tree and boulder to the side and gave a soft wristle, then lit from the perch he'd found and brought himself down to the blockage, treading the air (as one would tread water, yes?) He grabbed a rock in his talons and began beating the air with his powerful wings. In a show is strength worthy of a championship bird, he hoisted his choice of projectile into the air. He gained some height before swooping down for speed and using that to climb higher with less effort.
Below, Kawaken was putting the last few bubbles into his wall. Regan heard her bird at work, and knew the time to stand back was soon. "Good work. Return." With one safely in his ball, she just needed to safeguard Abra. She picked him up and looked around quickly, sussing out the best place to stand. "Probably riiight... Here." She nestled into a place nearby. A little space in the wall. Must've cracked from something.
She looked at Abra. "It's a good thing you can take care of yourself... You've got such a low presence, if you weren't so heavy, I might forget I was carrying you. Hmm, I wonder if you're doing that on purpose... Clever little Abra."
Rapier had gained a satisfactory amount of height. With a great effort, he began the toss. And quickly find himself following through immediately. Rocks are dense!
He tucked his wings in without thinking, just to keep up with his payload. He fluttered this way or that to line it up, carefully. He didn't want to lift this again. With a falcon's cry, he announced the impending crash and released the stone, opening his wings and peeling away.
"Oh, there it is! Here it-" The pile blocking her escape got smashed, some fracturing, many breaking. By no means did it remove the obstacle, but it crushed it enough to make a large hole. But man, it was loud! Regan had to orient herself quickly as she got Abra on her back. "Can you hold on for me? I need my hands."
She had to cheat just a bit to make sure she didn't fall because none of her foot or hand holds were secure, but Regan made her way up quickly. Once at the entrance, she hoisted Abra onto the nearest side of solid ground. "There, it's solid there. The whole tunnel's a sinkhole waiting to happen. I need to teach that Onix a lesson about where he's digging..." She was a bit out of breath, still only halfway out of the tunnel.
A roar from within the tunnel. "Conveniently, he may be coming to us."
