Cerulean Cape there's your obstacle.

Penn gave his coat a hard shake, annoyed by the light, misting rain that kept his fur uncomfortably damp. A chill ran along his spine as he paced along the cold sand, gazing out at the sharp waves that made such a ruckus as they crashed into the shore. He was only kinda sorta trying to avoid the waves, not coming close enough that they overtook him, but feeling free to walk close enough that they'd catch him up to his knees every so often when he didn't dart quick enough out of their reach. It was a game, but a boring one. He could've made it much more interesting, but he was distracted at that moment by the aching hunger in his gut.

He turned away from the waves, peering ahead and to his right as the clusters of rocks that lined the beach. He kept his eyes peeled for seagulls trying to keep cover from the weather, but he wouldn't limit his options if something else happened along. Not that he knew what that something else could possibly be except maybe more seaside birds. Or maybe that weird thing that was skittering across the sand ahead.

Wait, what?

Penn stopped, staring at the creature with wide, curious eyes. He hadn't spent too much time in this sort of environment before so he'd never seen anything remotely like a crab before. He wondered at first if it was some sort of frog, but it was flat, and it was... There were no words.

The yearling watched it curiously for a few minutes before trotting forward to get a closer look, unaware that it had claws and he was very unlikely to appreciate that.
