On my Leo Dux from the Nero Rex Set's cannon, there is a swing down tab that looks like it is meant to clip in somewhere, but I cannot find any indication where it goes online or in instructions. Does anyone know what it is for and where it stores in beast mode for any of the figures?
There's slots inbetween Tigris/Rampage's legs where his tail stores in robot/arm mode that the cannon pegs into, so that it becomes a back-mounted gun in Tiger mode. Talon technically has those slots too, but they wind up in useless places for all modes.
