Tameable plant!?

So what if we made a tameable creature that was a spore blossom. So the creature looks like a tortoise right but on its back it has a spore blossom and it’s body is made out of moss and cobble and vines and how it spawns is it pops out of the spore blossom like first it’s head pops out then once it’s fully out of the flower it falls and lands on its back and struggles to get up but then it rolls over and gets up and walks around, I also think it should be found in lush caves and it is vegetarian like it eats glow berries? And it can shed things like shards, armour trims (very hard chance) and glow vines (common chance) and you can ride it but you don’t need a sattle you can lead it around with another new item a glow berry on a stick and you can use carpets to make it look good (like lamas) and when killed it can drop any plant that is found in lush caves and it also attacks hostile mobs that are near it (or near you) and if you breed two of them together you get an egg but when it’s just hatched it is an egg with four tiny legs and during the time it is growing it gets out of the shell, and it attacks by opening its mouth and (like the frog) uses their multiple tongues (vines) and attacks the opponent, it sounds like a chirping sound and when you feed it until there is hearts it makes a cute squealing noise, you can also have the option to pet the animal and how you tame it is to feed it moss
