Did you look into the gumball machine?

Great. Now, get some change and get the ring from the gumball machine. I think you have a good change of getting it.

That stupid wombat! Go beat it!

You need more audience to man up!

There's the bunch of junk knights. Maybe they are up for a job. Go talk to them.

They are waiting for the prophet to finish on his task, first. Help him to finish.

Great. Now go and offer the job to the knights. After they are with you enter the labyrinth.

You have to fight the wombat. Hint: grab the glass shard from the floor and throw it multiple times at the wombat to kill it.
