What's wrong with Flashfire? Part 3

The flying object has a splash landing in the water, and you fly up to see from above.

The object sizzles and steams as the water cools it off. It isn't a space ship, but it doesn't look exactly like a space rock either.

Down below, Blackfire and Flashfire run out from inside the house, your sister carrying her pigtails up off the ground again.

"What was that?!" Blackfire shouts up at you.

"I don't know," you reply. "We should check it out."

*WHOOSH* You fly towards the object, with Blackfire flying after.

*WHOOSH* Flashfire flies up, but she is weighed down by her long hair.

"Wait up!" she shouts. "I can't get proper altitude!"

"Then just wait at the house!" you shout back.

Flashfire grumbles as she flies back inside the rainbow house.

You and Blackfire draw close to the object as the steam dies down, and it no longer sizzles.

"If it's not a ship or rock," Blackfire asks, "then what could it be?"

Before you have a chance to answer, the object begins to move.

*CRACK KOOSH* Sections on the left and right sides of it pop out, and their shapes resemble arms of sorts.

*CRACK KOOSH* Another section pops out, and it is curved outward like a dome.

"Is it... Transforming?"

*CRACK KOOSH* Two more sections pop out, and they turn and unfold to become legs.

With the sound of cranking gears and pumping pistons, the object-turned-robot stands up, its full 40 feet reaching far above the trees.
