This is level 11 of The Crystal Gallery.
Once again, every character would be fine.
The Runner is good on everything, so I don't even need to cover her. Just do what you've done for the past seven or so levels. :)
The Lizard goes slowly, and jumps high to a point where you can hit the wall perpendicular to you. Or just the left and rightmost walls. You could jump off the 'dead end' depicted in the screenshot and land.
The same goes for the Bunny, except it jumps even further, and you should zip through the level.
