Nobita wants to go to fishing because Gian and Suneo caught a lot of fish at the nearby river. Nobita asks his mom if he could go to fishing, but his mom says he is clumsy and can easily fall into the river. So Doraemon uses the gadget, Mobile Fishing Lake. But there is so much trouble using the gadget that they fail to catch any fish. The episode ends with Doraemon and Nobita landing in Shizuka's bath tub mistaking it for a hot spring.
- This is the first 2005 anime episode to have Shizuka interrupted while taking a bath.
- In the 1979 version, Shizuka has black hair, perhaps the only episode in the 1979 that has her with black hair instead of brown. Also, Gian's voice sounds a bit different than the rest of the 1979 episodes, and it is one of the first 1979 episodes ever produced.
