Hosting fun activities at the beach for visitors and such always brings in a variety of different crowds. Marine and Sticks are playing at a remote part of the beach far away from the crowd and messing with one of the human host of the beach they captured and shrunk down using the same device they "borrowed" from Tails They don't plan to eat or harm the human, but the two girls will still be making him be part of a kaiju set after they finish building a sand castle where Sticks will pretend to be a giant monster destroying the castle with him there...safely of course. He'll be forced to entertain both the Mobian children for a bit.
For the "Sonic Girls at the Beach" set this will be the only one with a fetish which is giantess and a micro present. Also I'm gonna have Sticks and Marine act as two characters that are always up to silly mischief when they're together to make things more interesting.
