Looks like a Ender Dragon. But smaller. It is not hostile nor is it large enough to fly.
Taming[]
You can tame it by feeding it warp bones. Once you do that it will stare at you, blankly. If you then feed it a ender flesh then it will have blue eyes instead of purple (or red if you attack it). Once that happens you give your dragon a name. This is so on a multi-player server other players dont mix them up.
Uses[]
The baby ender dragon is fed warp dragon meat from end traders or a recipie. Then feed it to your dragon and it will be happy entering love mode (only mates in tier 6 romp higher.) once you feed it 5 times it goes into the next tier:
Tier 1: Follows you but doesn't do much at all.
Tier 2: Kills enemies, similarly to a Wolf. Had 30 HP and does 5 damage.
Tier 3: More damage (10)
Tier 4: MORE damage (15)
Tier 5: Purple fire balls! (One per 3 seconds and deals 20 damage)
Tier 6: Can mate
Tier 7: Can fly!
Tier 8: E V E N MORE DAMAGE!!! (25)
Tier 9: More purple fire balls (3)
Tier 10: EVEN MORE MUCH MORE DAMAGE!!! FIREBALLS AND CAN CARRY YOU!!! (35, and 5)
what they do[]
they act like wolves. Except lead by a ender nest keeper.
They drop 1-3 dragon leather and 2-3 ender pearls on death. When damaged all dragons retrat to the nest and the nest keeper atacks you. These things are a part of Minecraft: the end has risen! mod.
