Sly's Easy Defeat
To easily defeat Sly in the "Lyre Lyre, Pants on Fire" level destroy half of his life points. Then use the Frostyrangs. If done correctly Sly should freeze and then break out and faint until his lifepoints have been drained.
Talisman Machine
If you battle Boss Cass before you've gotten all the talismans before that level Julius won't work his talisman machine because you get two at Cass's Crest.Sly gives you a at the last battle make sure you have three before the last level.
Talismans
To get all the talismans, make sure you have three before you go into Cass's Pass. Sheila gives you one in Cass's Crest. Sly gives you one in The Final Battle. I had two before I went in and now Julius won't make his Talisman machine work. I only have 99% done because of that.

Zap the birdie
Note: you need to have got the Zappyrang. Find one of the posts with a triangle on it. Let the bird appear but dont talk to him. change rangs to you zappyrang (if you don't have it on) and fire it at the bird. He should jump up in the air telling you to stop it and should change between a skeleton and solid bird. like what happens in moovies when they get zapped.
