There's that huge metal gate in the very back center of the krypt, i wonder if that opens up after something happens. Say, you get all koffins open, and maybe there's a secret character you need to find in each realm. Like how motoro is in earthrealm and gives you 1000 ruby and dissapears, and how meat is in neatherrealm and gives you 1000 onyx. Man i dunno.
also... someone help me find barakas alt bio already!! koffin GA... where can i get the key...
