**Codpaw**
This was actually fun; doing anything in the water made it that much more fun. He felt confident that he'd gotten the last move down well enough so he watched Sunsetbloom closely for the next move. He practiced the motions a couple of times, getting a feel for the resistance of the water, while he waited for Sunsetbloom to come around.
When she faced him, he lunged forward and reached for her shoulders. He grabbed hold (hope that's okay, otherwise play it as though he missed), but the drag of the water took him by surprise and he lost his grip before he could successfully pull himself up. His body bobbed back into the water so he got his footing again and reset.
"Can I try again? I think I've got it this time."
He tried once more. Getting a firm grip, he focused his strength on his hind paws, digging his claws into the river bed as Sunsetbloom had instructed, and pushed off the ground. The momentum carried him up out of the water and onto Sunsetbloom's back (again, hope this is OK otherwise RP as though he missed). He lost his balance and fell back to the water with a splash but he re-emerge happy that he'd gotten as far as he did with the move.
