Prince Adolf's first invention was a simplistic little wooden device with a light bulb & music box installed into it. The machine had a small red button that when pressed would simultaneously activate the light bulb which was used as a night light and music Box at the same time. the music Box played
"Brahms Lullaby"

The invention serves no practical purpose in Adolf's life other than being a toy for entertaining a baby Adolf and helping him understand the basics of tech. Like many of his early creations this machine was preserved in his secret Laboratory.Adolf was 5 months old when he made it, And still remains his most sentimental creation. Because it was his first.

In successful acts Adolf has saved this machine from
being destroyed by his sister
