The Citadel of Chaos

You take out the Jar and, as you do so, the Ganjees gasp 'Racknee!' says a voice.
'You have returned!' And with those words,
an invisible hand snatches the jar from you, lays it onto the ground and opens the lid.
The Spider-Man turns towards you and growls a little growl.
You draw your sword as the beast scuttles towards you angrily.

You must fight the creature:

As soon as the Spider-Man gets its first hit on you.

If you win without it wounding you, you must now face the Ganjees with your sword..
