It's hard to say whether or not Cetus does like to take walks on the beach, but he does every so often to relax from swimming all day in the ocean.
Leaving behind some footprints on the sand with each step, he doesn't seem to mind at all. That was until he hears some crunching underneath one of his webbed feet. And it was Chaos and his Sceptile buddy, who just so happened to be in the way of Cetus's huge feet. (Hey, there were pretty small compared to the giant 300 metre anthro blue whale, so it only makes sense.)
So Cetus thought, "Oh good, more bugs to squish...", and did what he did best by trampling down on the two tinies.
In the end, he scrunched up his toes, probably to tease the two for more stomping inbound or to get the sand off the webbing of his feet. Either way, he's got plenty of fun with them...
