Horseradish Hill is the first level in Tuberia. Keen will need to pass it in order to get to the main body of the map, though it contains no Boobus Bombs.
The level structure is rather simple, and the level can be completed in less than a minute. It has largely horizontal movement, much like the defense tunnels in Keen 5. Keen merely has to go left from his starting position until he reaches a wall, climb up the pole next to it, continue left, drop down and go left again to the exit. (A few enemies will need to be stunned along the way.) The level contains one extra life. It can be reached by going up to where the first Tater Trooper is, and jumping to the right, you will find a flowerpot. Jump off the right edge, and if you get the correct location, you will get the 1UP.
There exists an element of overkill at one point with four Tater Troopers on one platform. As so many Troopers are crowded on it, at least one may very well fall off the platform and onto the ground below when stunned. This makes the level harder as, once they turn into their usual selves, one must avoid Tater Troopers more often with no safe platform to jump to.
