Alfie decide to test the gun on himself.
He could he zap himself with the gun set to grow, he could grow to the size of a giant, and stomp around the world. he could smash buildings, cars and trees at the size of a 50 foot giant.
Being gigantic would make him unstoppable!
Or he could zap himself with the gun set to shrink, he could shrink to small sizes - to doll size, to ant size, and he could make sneaking around a whole lot easier, since no one would notice a small doll-sized burglar.
of course, He always wondered what it'd be like to be extremely tiny. He especially wondered what it would be like to be nearly microscopic.
Being tiny would be cool!
but then again, he could try the age option
For age: he could regress or progress in age for a disguise. after all; Every burglar needs a disguise.
he could also swap bodies with one of the cops, to see what it was like to be on the other side of the law.
he could become a female woman, or he could gain extra muscle!
despite the fact he was in a tight space, he managed to activate the gun, and he activated the _____________________ setting.
