Sir Dominoes are seen mainly just walking around. A single Sir Domino can be found in the Testing Room alongside a Kasplat and two Mr. Dices. Sir Dominoes only attack by running into a Kong. Sir Dominoes tend to run faster than Mr. Dices. Large Sir Dominoes can also be fought in the R&B Room with Chunky Kong only. However, overall, Sir Dominoes are very weak enemies and can be taken out with the simplest of attacks.
- Sir Dominos are also used as feet for the Toy Monster.
- It is unknown if the Sir Dominoes work for King K. Rool. However, since they are found in Frantic Factory, a level located within K. Rool's Mobile Island Fortress, it can be assumed so.
