Inventory Pets is a mod that adds different kind of item pets to your game, that spawn in chests in clouds in the sky.
Repurposed structures adds structures from vanilla minecraft, but makes the structures for different biomes but makes the structure give the theme for that biome. For example a desert woodland mansion.
Please let me know if there are any other mods I could add!
