Suprise game in an hour, looking for a one shoot

[BloodSnake'sCha]

Hello guys :)

Our DM for tonight is sick and another group member and I are trying to make something fast(the first one to make something will DM it).

I have an hour to make something, any recommendations for a oneshot?
Any level is great, it will be around 4-5 players, all experience players.
Prefer something not from a hard cover as we played most of them or running them right now.

EDIT:
Found something nice online but the other guy finish first so he will be running the game today, not need for recommendations but I will still be happy to get some :)

If you still have time, I came across this weird dungeon themed after microbiology. It has tardigrades, giant dust mites, and an amoeba god! https://imgur.com/a/ysR32KM

I saw it in the past but lost the link.
Will totally make it for the next time we have a sick DM.
