|Artwork of Pukapucker from Mega Man 5.|
When Pukapucker spawns, it will walk 4 tiles forwards and then 4 tiles backwards, and then repeat the behaviour. While it is doing this, the enemy's spear shaped head will hover up and down 1.5 tiles high at regular intervals. If the head collides with a ceiling when hovering upwards, it will reverse direction and hover downwards.
If Pukapucker's head is attacked and destroyed, or is despawned by traveling off-screen, its body will also be destroyed.
If Pukapucker's body is attacked and destroyed, or is despawned by traveling off-screen, the head will continue to travel in its facing direction, bouncing up and down on the ground 4.5 tiles high. If the bouncing head collides with a wall, it will reverse its direction of travel. If the head collides with a ceiling when bouncing, it will reverse direction and bounce downwards.
- Pukapucker may be based on a Floating Ball Toy.
- When both Pukapucker's body and head are both alive, the head won't be affected by gravity, but its body will. It is unknown if this is a glitch or intentional.
- In Mega Man Maker, due to a glitch or mistake in the enemy's AI, when whole, Pukapucker will immediately reverse its direction of travel when colliding with a wall when it is walking to the left, but will not immediately reverse its direction of travel when colliding with a wall when it is walking to the right.
- When a Pukapuker's body is pulled by a Conveyor Belt, its head will clip through walls it collides with.
