"Aww its an adowable undead guardian!!!! I bet it would never hurt a living thing :("
The Adowable Guardian is a Vintage Item that spawns a special Zombie at your base (nicknamed "Zwambie") that explodes on touch with anyone not on your friends list, killing them instantly. The Zwambie also looks quite cute, tricking new players into thinking it is harmless. The cute zombie now has the ability to leap walls completely and effortlessly to find new friends to 'hug'.
Like the Undead Guardian, when the Adowable Guardian is placed, after about a second of it being placed, it makes this interesting sound that sounds like a little cute bug laughing, basically the same sound as the Undead Guardian, but a bit faster and a higher pitch.
