Iv'e had ideas of a sort of super milk molar which would, like the mega milk molar, allow you to access different kinds of upgrades. I like your accessory slot upgrade idea though, it's pretty cool and would make sense while not being to overpowered.

I just thought of a way to balance a combined trinket. Combining two certain trinkets would make a trinket medal (For example combining the infected broodmother trinket combined with the fungal growth trinket would make a medal) ; this would not combine both effects at the same time but instead you would be able to choose which effect to have. Combing all the different trinket medals would make the trinket medallion allowing you to choose which effect you want from any trinket.

I really like both of your ideas, i've been thinking that there could some sort of super boss trinket made from all the bosses' trinkets. Also, yeah it's pretty annoying when you find a random black ox beetle, start fighting it, then realize you have a dandelion tuft in your trinket slot.

I was also thinking of just one room such as the kitchen which could provide an entire freezer biome.

I've been thinking of this for a while but i've been wondering how new unusual ants could be introduced into the yard and got an idea. There could be an ant farm somewhere in the yard maybe fallen out of the house window that could bring non-native ants to the yard. This could include bulldog ants, army ants, or maybe even bullet ants. Really I just wanted to submit this idea to get the thought out.
