Virus Tensei (manga) - MC reincarnates as a virus, he can infect monsters, copy skills as "symptoms" and use them with the current host. Kind of fun, specially after

Isekai Onsen Paradise (anime, short episodes, currently airing) - onsen maniac dies looking for an onsen, and now teaches isekai natives the greatness of onsen. Yup. (There's another story where someone reincarnates as the onsen itself, but I don't recall its name)

Ride-on King (manga) - MC is the president of an Eastern European country, and he loves to ride critters. There's a good focus on worldbuilding.

I guess all three are in the "whacky but fun" tier? I need to check out the Villainess' Stat Menu one, that's weird.

“Reincarnated as a sword” and “Reborn as a wending machine” are whacky but very fun to read/watch

Agree for both. I really liked how they handled Boxxo being barely able to talk, but still smart enough to convey ideas by the seven stock phrases + releasing items. (And Fran+Sensei need more love!)

Actually just started reading the translated novel for the google spreadsheet one, so far it's a fun read!
