You come across a dip in the terrain near the meeting of sand and grass, and it doesn't take long to realize it's leading down into a small cove and the start of a sea cave! While it's not very large yet, you can see the surf is slowly eroding the space - some day, this might be a lovely lagoon, though for now it's just a much needed shady spot.
The glint of creatures under the water catches your eye, but the attention drift causes you to notice something else nearby. Growing on several rocks poking out of the water are some odd little fungi. You might be able to get them and bring them back if you try.
Optional. On success, +1 Weird Mushroom?. On failure, get bitten by a hungry pokémon and -1 HP for whoever attempted.
