Mega Titan is the boss in Carrot Castle.

Wheel

Mega Titan

 

The blue region is the recommended visual cue for emulator, while the green region is recommended for console.

There is a small window when wheel is active where jumping will hit Mega Titan from the left side. Alternatively, you can opt to wheel jump twice into Mega Titan from the right, at the cost of losing a second to using the further wall. Once you get Mega Titan damaged on the electricity once, time attacks into Mega Titan just as it gets up to push it back into the electricity and make short work of it.

Titan Head

3-cycle fight

Go near the corner, use Wheel, and then jump just before Titan Head reaches full health (do not wheel-jump otherwise you will get hit). Jump into Titan Head with your Wheel and turn around after dealing damage each cycle. You can beat it a little faster if you land 3 hits on the first jump.

2-cycle fight

The 2-cycle fight is an advanced method of beating Titan Head, however is quite precise to execute. It is done with the following steps:

  • Position the tip of your cap on the left shadow of the pillar to aid timing.
  • Wheel jump at full height the moment Titan Head passes the circular window pane in the background (a healthbar cue may be preferable).
  • Turn around after 2 hits and land 2 more hits (hardest part).
  • Cancel Wheel after the fourth hit. Don't hold left until activating Wheel.
  • Jump and then activate Wheel at jump height.
  • Turn around and jump as soon as you reach the floor.

These steps all require precise timing and positioning. The setup is intended to land 4 hits on the first cycle, and 6 hits on the second cycle, for a total of 10 hits (20 damage) to kill the boss. This saves around a second over a 3-cycle setup.

Cutter

Cutter is the recommended backup ability to use in case Wheel is lost. Land 4 hits with Cutter to push the boss into the electricity. From there, spam attacks to finish off Mega Titan. For Titan Head, land 3 hits, then use a star bullet from your discarded ability to finish the boss.

Including movement, Cutter loses around 4 seconds to (3-cycle) Wheel.
