Okay, here are another few things that you can get around the spiral :
In Colossus Boulevard, you can find a frosty tree in the middle of the road. Just swoop right in there and get it.
In the Tower Archives, you can fight Vilara Moonwraith and get a glowing Dragonspyre plaque.
In the Balisca, go to where Zeke is. He has a free Dragonspyre lava fountain waiting for you.
In the Mooshu World Room, you can find a standing column, right behind the door.
You can get a sofa & Nightshade's bones when you fight Nightshade in the Haunted Cave.
When you fight prince Gobblestone in Colossus Boulevard, you can get a pumpkin, and a food box. ( just in case you get a little hungry. )
In Krokosphinx, when you go to the shopkeeper that sells the Heck Hound pet, he has a free jar of tomatoes sitting next to his stand.
