Grounded 2 ideas.

[Goofydaog]

1) dual riders on the spider, incase your teammate is far away without a spawned buggy. 

2)should also add snacks/treats for the buggy that come with added abilities. I know there is some sort of glitch that keeps happening to me with the spider where I can jump 40 cm, having that as a legit boost would be awesome. 

3) to keep the game going you could also eventually add bigger and better bugs/armors/weapon/potions and even small animals like mice, rats, gophers, and even Little garter snakes, tarantulas, millipedes/centipedes, also should add in earthworms. 

4) allow the abilities to make some sort of headlight for your buggy and actual armor for your bug that give offensive and defensive traits to help them in fighting

5)give us some boxing gloves, boxing ring, bowling alley for our rec rooms!!! We need more entertainment.

6) we always see bones throughout the game like rat skulls and bodies let us use bones fragments from them for something!!
