Lava Ocean Spindle Flowers

A rare mob could hang over lava oceans in the nether. They could resemble a red/orange flower-like build with teeth inside and a long orange string they produce hanging down to the lava ocean. You could try breaking the string off, or what you could also do is go to the ceiling and kill the spindle flower. They can try to bite you which can set you on fire or poison you. Once you can kill the flower, it can drop its string and seeds for you to use in the overworld to hang them in a farm (on netherrack). This would add a new farm mob you have to be careful around and deal with differently. They can provide their string to use for new items. The farm spindle flower could also drop its seeds when fed meat.
