Its Gremlins so this is what I visualize.
Wong straps a big freaking rocket to a gremlins back, who then climbs into a Pigapult with a Stuffed Piglet.
They launch the gremlin and piglet out, planning on the gremlin to blow up the piglet, lighting his own rocket in the process and then hitting the flying thing.
Naturally it didn't work, but I imagine a rather pretty light show went off in the direction of the Zeppelin, probably even got close enough to make the people on and around the ship very nervous.
