Codename Kids Next Door: Operation Z.E.R.O. Outnumbuh'd! - Gameplay

I always enjoyed the sound track of this game

The zombies seem to be smiling all the time. Creepy.

I play this game as a kid growing up

I feel like I beat Toiletnator once, but I couldn't remember ever doing it. He was hard for sure lol

Bro zombie toiletinator was ruthless and they expected kids to beat this game
