My second mod is finished! Here is a link to the Cursed Bath!
Basically I modified the interactions to allow adult Sims (and mermaids) to “Take Strange Bath,” which increases their weight by about 10 points over the course of an hour or so in the tub. All other interactions with the tub (except repair/upgrades/etc.) have been disabled.
Let me know what you think! If you have any questions or ideas for new similar mods (particularly other existing objects to modify) let me know down below as well.
