The Lizard is recommended if you have already passed Level 40 or bought it in the shop. Its superior jump height and slow speed (which means high maneuverability for the Lizard) can let it jump over the large gaps, and able to walk all across the spiral shaped platforms, granting it an edge of beating this level. Most already have the Lizard, as for the sake of OCD they finish the Main Tunnel first, and do this next.
If you don't have the Lizard, you can use the Runner or her Jack-o-Lantern costume (750 power cells or beat the Low-power Tunnel) alternatively. Using the Runner, use the high long jump and you can slow yourself down by jumping while walking the spiral shaped platforms. You can use the exact same strategy for the Lizard while using the Jack-o-Lantern, as the controls are similar.
Overall, this level should not trouble most players, as there isn't really a problem, but the design still makes it potentially a minor setback and frustration.
