It's been a week since my little experiment went awry. I, Tails, turned myself into a two-year-old in a bid to be the same age as my brother Phoenix.

Phoenix used to be Sonic, but after an incident with a youth fountain, he lost his memories and speed, and I've been raising him ever since.

Despite my physical age, I retained my adult memories. However, my new age frequently compelled me to act like a toddler.

One day, Phoenix brought a friend from school. They were engrossed in a video game when my toddler hunger pangs kicked in.

I toddled over to Phoenix, asking for a bottle. Phoenix's friend stared at me, shocked. "Isn't Tails eighteen?" he asked.

As Phoenix carefully fed me, he explained our unusual situation. The friend's eyes sparkled with mischief. "We have to take advantage of this!"

He suggested throwing a wild party while I was unable to protest. He even suggested using my machine to become 21 to buy beer.

I tried to protest, but Phoenix promptly put a binky in my mouth, silencing me. The plan was set.

The next day, Phoenix's friend returned, pockets jingling with my coins. He had used my machine to age himself.

He had also bought the beer. I could only watch as they began setting up for the party.

As the party began, my toddler instincts kicked in. I found myself enjoying the loud music and flashing lights.

However, as the night wore on, I began to feel uneasy. I realized the party was getting out of hand.

I tried to grab Phoenix's attention, but he was too busy enjoying the party. I knew I had to do something.

Despite my small stature, I managed to reach my machine. I knew I had to revert to my actual age to control the situation.

With a little tinkering, I turned myself back into my 18-year-old self. Relief washed over me as I regained my proper age.

Now that I was back to normal, I could handle the situation. I started by turning off the music, gaining everyone's attention.

Seeing their surprise, I explained the situation. I made it clear that the party was over and everyone had to leave.

Phoenix's friend was the last to leave. He looked at me, confusion and disappointment in his eyes.

I apologized for ruining his fun, but made it clear that my abilities and possessions were not for misuse.

After the party ordeal, Phoenix and I cleaned up. I turned him back into Sonic, restoring his memories and abilities.

It was an emotional moment. Sonic hugged me, grateful to remember his true identity. But he was also sad to leave his child self behind.

I reassured him that he would always be my little brother, regardless of his age or identity. We shared a tender moment.

The next day, Sonic and I were back to our usual adventures. We learned a valuable lesson about age and responsibility.

As for Phoenix's friend, he learned his lesson too. He apologized for his actions and promised to respect others' possessions.

Despite the unexpected age regression, we managed to turn it into a learning experience. We grew stronger as a family and as friends.
