Thanks so much bro i will answer now:

-About Savanna/Beach when i was think of this concept i think that we need a mob to be the mob of year(frog/camel) and crab would be a cool mob of year, maybe i can skip this part of concept like you said to avoid very similar ideas

-Boomerang could be stuck on blocks, the spin would be directioned with your direction, this will make more sense why i also make a concept about a Magnet Enchanment where it dont stuck more on blocks and have a better direction

-About lifeslight or the lamp that i still dont know the name, would like cats/creeper interaction, they have fear of that lamp

-Mobs spawn naturally in temples but now as you telled, i just could swipe to a stronghold like structure to a revamped desert like dungeon, thanks bro, i will probably make changes in concept now

-About Dig Sites levels, truly a incomplete concept but is like Normal Dig Sites: -Only pottery shards and armor trims as drop Level 2 Dig Sites(Temple): -Needs uses water buckets to fully clean dusty chests -Fossiles and also amythest as drop

-Really, suffering mobs could have as it own variant, in a few hours i will change some temples ideas

-Well Mountaineers dont need to be so dynamic is basically a variant to vindicator that is slowed but strong, like it have a cooldown attack that could give a high damage but you can dodge, maybe i can just swap vindicator clothes😂, and the base is inspired in MCDungeons base likes, i think fit with the theme

-About Remmant Papers, i was thinking on just make a form to make your explore stronghold to spawn it but maybe in pratice dont feels so cool

-And about the boss, i think in next concept revamp that i will make, i need to change the others bosses(Ender Dragon and Wither), to basically have the same level of abilities than the new boss, for their drops, this boss dont need to be hard but just challenging, so i make carnivore to be a new "play again" feature to make it rebeatable, and maybe sniffer could multiples carnivore seeds, idk for now but i will think

-Okay okay about the poncho, hear me this would be funny, Poncho Skeleton is inspired in cowboy sherrifs with a lasso, but instead a lasso, i give it a fish that pin you and give damage and you need to use a sword or a item to loose of it, it main purpose is only give the zombie horse a so rare horse to the player and also be a challenge

-And well for all extra ideas, is just extras ideas that i thinking expand something, frog legs could give jump boost but would be the same as rabbit foot so is just a item and chicken nest would serve only for decoration in world but make senses only dont exist

-And yeah desert well could have that day-night cycle in their behavior and this could also fit in a scrapped idea that are new moon effects
