Stinkbug

We can't trade creatures u will have to catch it by urself

We can, however, trade bug models. You’ll have to catch the bugs yourself and talk to Flick on your own island due to how the game’s programmed, though.

Or someone else can prepare a bug model and trade it with you 🐞

Yes, both Advise and Stephanie are correct. If you are looking for a stink bug model, I think I have one in storage.
