do a undertale marble race or or get dunked on

i think you should do a Fan Marble Race with custom marbles

1. marblecosathlon party, where there are 18 cotestants and there is a marble race with them and each of them represent a game (for example race to the bowl or marble derby) and you get points based on how good you are one with least points is out
P.S. The contestants are marbles not humans
P.S.2. Give credit to me if you make this.
2. Objectdecathlon, where circles and squares and gears (there are other stuff but these are most common) race in challenges and one gets out.
Give credit to Ultragamer564 if you make this.

A murder mystery?
