life sized Robusa

I really wanna make like most of his characters but most of them are too tall BUT there are still a few I can do

but I wanna make characters of other people too

why is he happy when Drillcar isn't around

maybe he's going insane hm

also speaking of Drillcar, I would like somehow making him so that Robusa can sit inside him but I'm not sure how to do that so I might just not unless someone helps
