I really loved having aphids as pets in the first game and its a bit dissapointing that we dont have them here. It would be cool if we could also farm bugs like aphids and weevils to make getting food easier. I'd love if we could have caterpillars as buggies, I think they could work as a hauling buggy, essentially, being slow, but having a large hauling capacity, and more inventory space than other buggies. Another idea for a buggy is a bombardier beetle, which could be used to smash rocks, and have ranged attacks. Id also just like to be able to use weapons like staves and bows on buggies.

 

I would like there to be a rare type of gnat or aphid (special color maybe) you can tame and if you bring it around with you, it can retrieve arrows within a decent range, including the ones that have fallen beneath the map. Not being able to pick up those arrows is driving me nuts. While they could let regular aphids and gnats gather arrows, I think it would be more fun for there to be some rare versions of pets to find that have some sort of extra perk. 

(While it would be better for the arrow to just not fall through the map, even Grounded 1 never fully fixed that glitch.)

it's possible it's in the works, most likely Winter update alongside Mushroom 2.0, when mushroom slurry should be added
