Thanks for the report! The coconuts were there all along, but they were hidden behind the palm trees. That's fixed, arriving in the next update: they'll hang in plain sight on the trees in every Florina Beach field (not the town itself), ready to knock down. The Sea Trash is a different story. It only washed up inside wooden crates during an old beach clean-up event, and those crates aren't on the beach yet. We're working out how to bring them back, so I'm leaving this open for that part.

Good news on the Sea Trash too: the old clean-up crates are washing back up on Florina Beach, arriving in the next update. You'll find a few wooden crates sitting on the sand in every part of the beach, the town included. While you're on either "Cleaning Up the Sea!" quest, smash a crate (it takes a few hits) and there's a good chance it holds the Sea Trash you need. A broken crate washes back up again about a minute later. Together with the coconuts now hanging in plain sight on the palm trees, both items can be gathered. Thanks for sticking with this one!
