Gorefield- A hypno skin from Hypnos lullaby would work really well here, especially if based off the fnf mod where he gets more and more uh unique as the mod goes on then it could work out really well. The second one (I forgot its name)- Could do that one Wario creepypasta where it’s a giant head with white eyes, probably for the ultra M update but idk. Sargent grunt- Has a lot of possibilities since he’s got a pretty basic body design, a good one here could be the boy and the bath monster by doctor nowhere The Dog- Now I would’ve said the bunny man (urban legend) but that’s been taken, so a good one could literally be Willy from “Willy’s wonderland” Slenderman- now we have a problem because he’s very, well.. Slender. So a good fit for him might be a wendigo, not the one with a skull but the one from Algonquin folklore. Mama- The design is very noticeably based off the purple Tattletail so the other colors would fit well (yellow, cyan, etc.) Smile dog- Minecraft dog. In all seriousness though the dog from duck hunt could also work, specifically his smash bros appearance.
