Stickle

Stickle is an enemy that appears in Kirby Mass Attack. It is a relative of Blipper

Physical Appearance
Stickle is a teal, spikey pufferfish with yellow fins and a tail. It also appears to be wearing what might be sunglasses.

Behavior
Stickle first appears in the 7th stage in Dedede Resort. It extracts its pointy spikes while swimming underwater, making it almost completely invulnerable to the Kirbys' attacks. If the Kirbys touch Stickle in this phase, they'll take damage. However, if taken out of the water, it will retract their spikes and flop around, making them vulnerable and able to be defeated. There is also a medium and large-sized variant of this enemy.

Name of Origin
Stickle's name comes from the word "stick", which refers to a pointy object "sticking", or poking someone.
