Ultraman vs. Giganto the Big Space Monster from Space

Ultraman vs. Giganto the Big Space Monster from Space is some kind of LEGO short film created by a 12 year old The Boy Who Cried Godzilla at some kind of animation camp.

Plot
So, like... some kind of alien jewels get stolen by some pirate aliens so some green aliens go to Earth in this big mech thing called Giganto that... I guess destroys some stuff off camera because the Monster Patrol is looking for it. But then Ultraman shows up and blows it up. And then a whole bunch of aliens show up and then there is a shootout with some pirates before Ultraman unceremoniously flies off into space.
