Not sure exactly the point you're talking about but you could try using the mission transporter power to get there. If you don't have it, or don't have the money for it I can help you out if you let me know your global name here or via email ingame. @Skunk
Do they come from the actual head though? If so, my suggestion was to have the choice for alternate (already existing character hand) animations for powers that only use the head/mouth.
Suggestion to give Envemon and Neurotoxic Breath alternate hand animations. Was thinking the alt animations for Fire Breath and Ice Breath would work well for Neurotoxic Breath and the animation for Weaken could be used for Envemon.
