Once upon a time, there was a young boy named Timmy who loved going to summer camp. He had lots of fun swimming, hiking, and playing with his new friends. However, Timmy wished he could be as strong and muscular as some of the older kids at the camp.

One day, while exploring the woods near the camp, Timmy stumbled upon a mysterious bottle hidden under a big oak tree. The bottle had a label that said 'Mutant Caveman Drink.' Curiosity got the better of Timmy, and he decided to take a sip from it.

As soon as Timmy drank the magical potion, he could feel a tingling heat spreading through his entire body. His muscles started growing bigger and stronger with each passing second. First, his shirt began to tear little by little, unable to contain his newfound strength.

Not only did his muscles grow, but his pants also ripped, and his feet became huge. Timmy's hair started growing rapidly, covering his entire body. In no time, Timmy had turned into a muscular mutant caveman!
