The Corridor is the ninth and final level in The Halls of Undermountain. Stinky begins at the supposed "corridor" of the level leading to the exit, blocked off by wooden boxes. Loof can enter two side-by-side rooms via teleporter containing additional boxes, and buttons to bring Kaboom!s out.

According to the sign next to Stinky, this level requires patience since slow-moving Kaboom!s are needed to break through the exit corridor, and it is best to go one Kaboom! at a time.

Walkthrough

This level can be done intuitively for the most part, as the main aspect of it is about patience. It also should be noted that all Kaboom!s in their confined room turn left along walls, relative to their direction. For each box to destroy in the corridor, Loof must be used to open up passage for one Kaboom!, and Stinky must box it in.

The "Blocking Box" for efficient Kaboom! navigation.

Below is a step-by-step guide for each box to clear out of the corridor, one for each Kaboom!:

1. Collect the first two rainbow coins and push the first box in any corner. Push any box outside of the corridor into the other corner. Position another outside box so that the southern Kaboom! passage is blocked and Kabooms! can walk along the Corridor's walls (You will need this box later). Release one Kaboom! with Loof and box it in with Stinky to break the first box in the way.
2. Using the last free box in Stinky's side, release the second Kaboom! and trap it inside the corridor the same way as before to destroy the second box.
3. At this point, Loof needs to push boxes along a conveyor belt so that Stinky can use them. While keeping the blocked passage intact for other Kaboom!s, push the blocking box out and over to the corridor area. Then use Loof at the south end to push another box onto the conveyor belt. Use Stinky to push the new box to block the same passage again. Release the third Kaboom! and clear the third corridor box by boxing it in as well.
4. For the fourth Kaboom! and corridor box, repeat the same procedure as the third one. Do not collect the last two coins until the whole corridor is open.
5. Unblock the southern Kaboom! passage and get it set up for the last corridor box. Bring Loof to the north box room and move a box along the conveyor belt. Use Stinky to push that box back to the south Kaboom! passage to re-block it (use the teleporter). Release one more Kaboom! and destroy the last box in the corridor with it.

To get the bonus coins, Loof should still be staying put while one more Kaboom! is walking around its room. To ensure the safety of gathering the coins, have Loof hold down the button to open the gate, and immediately let go of the button to destroy the Kaboom! in the middle of the closing gate. Re-open the gate with Loof so that Stinky can collect the coins within. Is it now safe to bring both Stinkers to the exit.
