This game truly is amazing and I can't wait for all the future content. I've got some ideas floating around my head that I honestly just want to get out there.
The first idea is my current favorite that being a daddy longleg. I imagined it's oval like body just making it above the grass slowly making its way to where ever. I don't fully know how it would work out of course but my hope would be for it to be large enough to walk under and maybe play more of a role like the ladybug. Some crafting ideas with it would be a much further reaching spear hopefully to help with the reach the wolf spider has.
My next one would be a snail. I've seen an empty shell just outside the mysterious machine. I'd think it be a nice addition. It won't be killable right away because it might just hide in it's shell. The picnic table could have a spilled salt shaker somewhere nearby that you could shovel. With the salt you could make a salt bomb that shrivels up the snail or temporary stuns other bugs. The shell once cracked with a hammer (teir 2 maybe) could be used for armor or maybe a shield.
Anyways those are the two biggest ideas I've got right now. Obviously you can tell me what you think but I will love this game no matter if it has this or not.
