Woah! The sixth set is here! Sorry for the extremely long delay! I've had a lot to deal with recently. ;~;
This pack contains six Creepers; two Dispenser Creeper variants, two Dropper Creeper variants and two Observer Creeper variants.
The Dispenser Creeper and Dropper Creeper have a hidden door on top of their heads that can be opened by rotating the "Top Door" part on the X axis.
The pulse on the back of the Observer Creeper's head can be toggled on or off using the "Active" part.
