Play the first level. Get past the second dragon by rushing into the room and shovel down through the bricks as quickly as possible. When you hit the ground immediately use the Phase Locket and run through the bubbles. Then, bounce over the dragon and get past him. At the Boss, kill him by repeatedly hitting it with the Flare Wand. Note: You can also earn "Sparker" by getting him down to half a heart then finishing him off with a sword spark.
