Colossal Waddle Dee is fought as the first opponent in the Grasslands. It is in the normal category and must be defeated before the player can access any other bosses. The boss stomps slowly across the ground, and can also stop to pose in various ways; these poses include sitting down and tapping its feet, shaking side-to-side, stomping its feet like a sumo wrestler, and waving at the screen. It can also leap into the air and crash down on Kirby and his team. It does not get any new abilities after half its health is depleted. The boss is not much of a threat.
Colossal Waddle Dee is fought again in the Ruins and the Volcano, now as the first member of the Colossal Double-Team and Colossal Triple-Team, respectively. It no longer has a second phase.
This huge Waddle Dee has an equally large spear to extend its reach even farther. Don't let it run you through!”
— Colossal Spear Waddle Dee Quest Description • Super Kirby Clash
Colossal Spear Waddle Dee is a variant of Colossal Waddle Dee that wields a spear with a purple cloth tied around it, and debuts as a boss in Super Kirby Clash.
Colossal Spear Waddle Dee first appears as a boss in the Seaside. It slowly walks its way along the ground, occasionally throwing a spear. Like Colossal Waddle Dee, it also stops to do various actions, such as shaking its arms at the screen, sitting down, and stomping its feet. When at half health, it can now twirl around its spear before stabbing it forward, and leap into the air to crash onto Team Kirby.
It later appears as part of the Colossal Double-Team, Colossal Triple-Team, and Team Colossal Quad, where it does not have a second phase and has all of its previous attacks from the start. It also now throws three spears at once instead of just one.
Colossal Waddle Dee has suddenly gone berserk over in the Grasslands... We don't know what to do! Can you stop the attack and save our kingdom?”
Thank you for defeating Colossal Waddle Dee! But many more enemies continue to rampage throughout our land... We must rely on you, Kirby!”

Colossal Waddle Dee's model in Team Kirby Clash Deluxe is largely reused from Kirby's Return to Dream Land, while Colossal Spear Waddle Dee's model in Super Kirby Clash is largely reused from Kirby Star Allies. Their animations are new, however.
Colossal Waddle Dee's waving animation in Team Kirby Clash Deluxe is the least common one he shows, and it can only be seen if the player chooses not to finish the boss, thus dragging out the battle. The Waddle Dee drops its angry expression and looks more cheerful during this animation, indicating that the wave may have been intended as an Easter egg.
In Super Kirby Clash, Colossal Spear Waddle Dee may also wave at player, dropping its angry expression.
Colossal Waddle Dee is one of two bosses in Team Kirby Clash Deluxe to not reappear in Super Kirby Clash, as he's replaced by Colossal Spear Waddle Dee. The other is Dark Taranza.
