"The Time Slipper" (mention only)
The Birth of Arale!
Urashima Tarō makes an actual appearance in the film Dr. Slump and Arale-chan: Hoyoyo!! Follow the Rescued Shark..., where he appears to be dressed more like a Wild West prospector than a Japanese fisherman as the original story states.
- In Dr. Slump, Urashima Tarō has the same character design as Master Roshi from Dragon Ball. Roshi is in fact based off of the actual folklore character of Urashima Tarō.
- Also in Dragon Ball, Goku rescuing Turtle and returning him to the sea is a reference to Urashima Tarō's story (Bulma even makes an in-joke about it).
