Pocket Watch

After finding an old pocket watch inside their grandparents' attic, Leslie, a 13-year-old teen, decided to keep it due to their habit of collecting anything they deem fascinating (which can be anything in their case).

However, during a blackout which was caused by a heavy thunderstorm, they slipped unintentionally into a multiverse of a video game that is known as UnderTale.

While traveling through the multiverse with the goal to return home, they encounter friend/allies, frenemies, and foes.
...
Though they never thought that they would be accompanied by a chaotic neutral parasite who is a 90's nightmare, a psychotic yet very affectionate goat mom, a messed up yet friendly glitchy skeleton, and a laidback chocoholic.

This will be either quite FUN or everyone is flat out screwed. Heh... Maybe both.
