The Kukku Walker is the first boss in Tails Adventure. It is a green bipedal walker created by Battle Kukku Empire piloted by two Rock Throwing Combatants. The player encounters it at the end of Poloy Forest.
At the beginning of Tails Adventure, Poloy Forest is attacked by Battle Kukku Empire where a Kukku Walker sets the forest on fire. The Kukku Walker appears in the third segment of Poloy Forest, where Tails eventually encounters it.
The mechanical walker's pattern is simple: it will spout flames from its flamethrower, which the player can avoid by using the Heli-Tails ability. Another Rock Throwing Combatant behind the other in the front will also fire its own flamethrower if the player flies over the walker to the other side. During the battle, the walker keeps walking forward while spouting fire. After reaching the left side of the arena, it will pull back to the right side and repeat the pattern. It takes ten Regular Bombs to destroy the walker.
