Burst Screen 9, 10 - Yoku Blocks

Screen 9

This screen has some spikes and Yoku blocks.

Have Rush Jet equipped, the difference in the strats is when you summon him.

Safe Strat

You can summon Rush Jet from the right of the first high platform. Just get to the top of the screen, get past the blocks before anything weird happens.

Faster Strat

This strat is faster by introducing some more slides, and being lower on the screen. 

Jump from the high platform to the first yoku block, and slide off to the low platform. You will make it just holding right through the slide.

Summon Rush Jet on the low platform, then ride Rush to the end.

Screen 10

Keep Jet equipped. Jump over the Frogs, one at a time, and get to the next screen.
