Lenny Loosejocks in Space/Uranus

Uranus is one big maze of ladders and levers.

The key to navigating Uranus is the big master lever on the top level. Using it controls the extending bridges on the top and middle level. However, if you use it you will always be denied access to the middle area.

To further complicate things, there is a pair of goo pipes that either block access on the lower path or covers the ship in goo. The lever in the top right area switches which pipe is active. Since you need access to the lower path, flip the lever for now.

The trick is to find a route around the missing bridges. The bottom area has such a path, but the extending bridge needs to be extended from both sides. Go the long way around first, extend the right side, go all the way around again and flip the left lever so that you can finally cross. Assuming that you flipped the goo pipe lever, the path should be clear to the middle area.

On the middle area is a teleporter, step on it to reach the bomb.

Disarming the bomb
With the bomb disarmed, note the digit that appears and take the long route back to the master lever. With the master lever once again flipped, you can flip the goo pipe lever to clear access to the space ship. With the ship once again clear, you can just walk back to it and leave the planet.
