- "????: Oh hey how's it going? Ahh, it's nice to get that helmet off sometimes!"
- His sprite model is named "Fish Head". He also has the same frames for his standing and running animations as Shovel Knight.
- The Custom Knight included with the Shovel Knight amiibo can acquire a costume named Fish Head. This costume replaces Shovel Knight's helmet with the fish head of ????, making them similar in appearance. It also comes with custom dialogue portrait and character model for the map.
- With this unnamed character taking the same appearance as Shovel Knight, many people speculate that Shovel Knight himself is actually a fish head character. It is hinted to be a simple joke put in by the developers.
- This is also referenced on Yacht Club Games' s official FAQ, where one of the questions is "Will Shovel Knight eventually become a Mermaid?". They answer: "Oh! I thought you would never ask! We’ll just have to see!"
- Many crossovers and special appearances have also touched upon this idea. Shovel Knight's appearance in Rivals of Aether gives him a secret taunt where his helmet accidentally falls off, revealing the fish head. It is currently unconfirmed if this has anything to do with the ???? or the canon version of Shovel Knight.
- In an official series of merchandise statue by First 4 Figures, Shovel Knight's head can be swapped out with the Fish Head. There is also a golden variant for the Ornate Plate edition. It is still not stated, however, if this is Shovel Knight's appearance under his helmet.
