Rattle Battle

Difficulty:
 * Safe: 4/10
 * Optimal: 5/10

Safe
Notes
 * This level is infamous for its horrible hit-boxes.
 * Rattly keeps his speed while in the air, and when jumping on enemies. He loses speed when he lands on the ground. It is better to do long jumps over short ones for this reason.
 * At 0:33, you slow down to assure that the your speed will line up properly with the three incoming Kaboings.
 * At 0:48, you abuse the fact that Rattly constantly does little hops by himself when on the ground. When you have him do that while falling from the edge of a platform, you get a boost that you can jump out off.
 * You can do a goal swap if you use Dixie for the beginning of Slime Climb, but the safe route uses Diddy.

Optimal
Additions
 * At the beginning, go for a fast door. You avoid it in the safe route as it is tighter than other fast doors, and having Diddy stop his roll is an easy mistake to make.
 * At 0:33, you do not wait; you pray for good RNG so that you can jump on all three Kaboings. If you get bad RNG, just take the hit and keep going. There is a DK Barrel on the very next platform.
 * At 0:45, jump further to the right, but make sure you do not get stuck in the wall (the camera won't follow you if you jump too high). This allows you to jump under the Kaboing instead of waiting for him (Saves ~.5s).
 * At 0:49, edge boost yourself on the barrel to be able to jump onto the next Kaboing. Read the Safe route notes for more info on edge boosting (Saves ~.4s).
