The is part 5 of the Plan C tunnel.
In this level, you'll notice right off the bat that there are many gaps, which should be a hint on who to use. As the Pastafarian, you can just decide to not move and run across many holes, until you come across a large hole from the light bridge. You can move or jump to get out. One thing to note is that this strategy relies on keeping the light bridge intact, so try to do that at all costs.
If you don't have the Pastafarian, then you can use the Bunny. It might require some luck and memorization, but you can skip large portions of the level with its big leaps.
