So basically new characters are pretty much entering the frame. Such as Mr. Puzzles, Leggy (probably wouldn't count since it's still a Meggy), and Mr. WPNZ.

You know, SMG4 has a lot of characters. Here's a thing. Are we gonna add these new characters? Well, apparently no. I don't want to cramp up a lot of space. So Mr. WPNZ, Leggy, Mr. Puzzles, most of the characters will not be added to the roster unfortunately. But rather being seen as such cameos. Like you see Funtime Freddy, Bon-Bon, Candy Cadet, Phantom Chica, etc. in the Office on UCN. But as that being said, Not every character from the SMG4 Series going to be in this game.

This game is still coming soon!

EDIT: Another reason why this wasn't added, because this was in development since the Western Spaghetti Era
