Munchkin's Dice Bag "Special Rule"

[orcbgone]

I recently picked up the Munchkin Dice Bag, and I was wondering, does the bag's special rule only apply to standard d6? By that I mean Munchkin head d6.

Does it apply to these dice:

• Munchkin Jumbo d6
• USAopoly's Munchkin Adventure Time d6

The former because of the imagery used on the jumbo d6 and the latter because of Jake's face in place of the normal Munchkin head.
