Giygas- Starman Jr as Pokey

Then, suddenly, from the shadow of a large tree...
	“Picky! Ness! ...Oh thank goodness. I thought I might find you around here.”
...It was Pokey! They couldn't see him very well in the dark, but he appeared to be wearing an exaggeratedly gallant and virtuous expression on his face. “I've been looking all over for you,” he said. “Little children shouldn't be walking around out here so late at night. Let's go back home, quickly.” He turned and began to walk down the path.
	“What are you trying to say, Pokey?” asked the very puzzled Picky. “You're the one who forced me to go with you to see that meteorite!”
	“And is the Ferrari okay?” Ness added. “It looked like you were going so fast...you didn't hit anything, did you? …And besides that, what do you mean 'go back home'? Aren't you heading toward my house right now?”
	As he turned to face them, Pokey wore the expression of someone who knew they'd been caught in some sort of lie, and he shook his head from side to side.
	“Well, isn't it natural for me to want to escort a friend home, first?” he said. “I am bigger than the two of you, after all.”
	Ness and Picky exchanged glances.
	“Something's strange, here.”
	“Very suspicious. Are you...really...the real Pokey...?”
	“Heh, heh, heh...am I...?” Pokey smiled bitterly. “You foolish little children. If only you had been obedient, and gone along with it all, it wouldn't have ended so frighteningly for you...heh, heh, heh...ahahahaha, EEYAH!”
	“Whoa!”
	A star shower began to rain down around them. A gust of wind burst forth, and Pokey's body shone like a flashlight. Ness quickly leapt in front of Picky to protect him. Putting his hands on his hips, the chubby Pokey gave a powerful, boastful laugh, and in that bright light, he began to blur and distort until he had morphed into a very tall man, wearing something that looked a bit like a deep-sea diver's outfit.
	<Starman Junior!> Buzz Buzz gasped. ...Or rather, he had a thought that was like a gasp, and this ragged exclamation was sent straight into Ness's brain.
	“Heh, heh, heh, it's been a long time, Buzz Buzz,” said Starman Junior, as he raised one of his arms and thrust it forward menacingly. Apparently, his mother had never taught him that it was impolite to point.
