Mr. Tick-Tock is a circular, clock-like foe. He attacks by generating a sonic force field that sends forth musical notes. He draws inspiration from both real-life alarm clocks and decorative Nutcrackers. His moustache and eyebrows appear to resemble hands of a clock. He has small blue limbs, a reddish, round button-nose, and cartoonish white gloves. He also has attached to his head what appears to be either a bright yellow telephone or two school bells.
In earlier depictions, namely Kirby's Adventure, Mr. Tick-Tock was entirely blue.
Mr. Tick-Tock appears as a recurring mid-boss in these games. He jumps around haphazardly in an attempt to crush Kirby. He can also create a force field of sound (in the form of an alarm) around his body by forcibly ringing the bells on his shoulders. At times, the sound also creates musical notes which can be used to shoot back at him. If Kirby inhales him after his defeat, he is awarded the powerful Mike ability.
Mr. Tick-Tock appears alongside some of the other mid-bosses from Kirby's Adventure and Kirby: Nightmare in Dream Land in the new sub-game Revenge of the King. He is first found hidden in a secret area in Illusion Islands, where he can be fought optionally, and then shows up later in the final level of the sub-game, The Revenge. The second time Kirby encounters him he is not optional and must be defeated in order to move on. Mr. Tick-Tock is also fought in The True Arena alongside the rest of the retro mid-bosses. In this game, his force field ring attack makes a sound similar to a phone. Otherwise, however, he behaves the same as he did in past games. Kirby can once again get the Mike ability from inhaling him.
- Tick Tock Jr. seems to have been modeled after Mr. Tick-Tock. Conversely, Mr. Tick-Tock's new coloration may be a tribute to Tick-Tock Jr., who featured the same colors, only inversed.
- Mr. Tick-Tock's second alternate color palette in Kirby: Nightmare in Dream Land is almost entirely blue, which matches his color scheme from Kirby's Adventure.
