in the newest form, it is possible, you just have to fly upwards towards the faint red dot with FULLY maxed flight, (even if it means you have to topne down the rest of your abilities) after talking to ingot, killing him at the first juice fountain and drink him to get his hat. you will eventually run into some of these giant orbs, and the one with a ring around it will have a door. after killing slithers you get her massive sword, which will kill the creator in one hit, (for context). still wont kill the koaldog though
