MDK 2 Development Team are Stars:
While playing through level 4 don't forget to take a moment to gaze at the 
stars in the large arena with the three Poopsy Generators. Be sure to kill 
all of the enemies in this room first so you can star gaze without getting 
killed. Now, using Kurt Hectic's sniper scope, zoom in on certain special 
stars in the sky (they are usually slightly pinkish in color). There you 
will find the crack team that made MDK2 possible gazing back down at 
you, along with their Wu-Tang Clan names. Submitted by lilRZA
