Dapled Forest improved

The Dapled Forest is what i think the coolest Biome in the Game but it is way to empty. So i thought you should add butterflys! If you kill a Butterfly it will drop silk, with silk the Player could craft a Glider. with the Glider the Player could have an allternative from the Elytra you cant boost yourself but you kann glide a from an Hill! It schould be also a Brown Bear able to spawn in the Dapled Forest it schould do that what a ice bear does and it schould fish for his Kids and if he Fishs an Enchanted Boock ore something it schould just drop it. The player could automate fishing with this Feature! Back to Silk you schould be able to make a rope it works like twisted wines but you could craft it and if you place it on the Roof of the cave and the player click on the rope it schould go down to the floor of the Cave. And that was alll of my ideas thanks for reading.
