You can sort of stop the anim just before he opens his mouth replace the it with an empty cave and then make the Dragon Separate using the one from the RTP, so he chases you...
I am using it to knock you back and breath fire and go back in the cave until you return wearing or holding a dragon shield or armour... Then using the example above, that he chases you... Also the blank Mountain cave helps as an add on to the tile sets...
I think this char set may be used a fair bit !!
