The Great Dane looked up at him and woofed, tail wagging, and then looked pointedly at a rack of old-fashioned clothing. They looked like costumes from an old movie, or some adventure set back in the past, like Indiana Jones. Luke went over to check out what was there. Almost everything was so dated and silly-looking that he would almost rather streak home. The only clothes that looked even remotely normal was a pair of dirty overalls with a tattered straw hat. Luke pulled the overalls off the hanger and held them up - still too small, but he'd probably be able to make do. He dropped the boy's clothing and pulled the overalls on, having to tug them up. They were made for boy in his mid-teens, and besides being tight they were also so worn they had holes in the knees. They were better than nothing, and Luke figured he could look for something better at his leisure now that he was covered. The Great Dane was sitting, watching him with a wagging tail as Luke buttoned the last shoulder strap. "What? You think I look funny? Well, you're the one who...."
Luke gasped and staggered as the floor seemed to expand under him. He felt disoriented, and realized that everything suddenly looked bigger. "Oh, no! What did this do to me!?" He ran to the dressing room and gasped when he saw himself in the mirror. "Dang! I'm Huckleberry Finn!" His reflection showed a coarse-featured young teen with a tangled mop of copper-red hair, blue eyes, big ears, buck teeth, and a splattering of freckles across his nose. The coveralls were just a tad too big now, but felt normal to Luke. He frowned and rubbed at a smudge of dirt on his face. A glance down showed he was now just as dirty as the overalls, with nearly black feet that hadn't seen shoes or soap and water in a very long time. If he thought about it, he realized he probably didn't smell too great either.
But he sure felt great. Luke had been putting on mass and muscle the past few years, and the difference in weight was very noticeable. He sure was not going to be as strong as he was at 18, but he felt light and springy like this. He grinned, noting the scummy teeth and traces of snot around his nostrils. Definitely nobody making him take a bath or brush his teeth.
There was a woof from behind, and the Great Dane pawed at the straw hat he had just dropped on the floor. Luke picked it up and looked in the mirror with a grin. "Yeah, I guess this will complete the picture."
