- Call-Back: Ninja Bonnie is back.
- Dirty Old Man: Subverted; the Ninja Elder at first acts like this, but then it's shortly revealed that the woman he's making advances to is probably just as old as he is.
- Famed In-Story: The Ninja village has a legend of how, in its time of need, the village was saved by a group of ninjas, led by a peculiar-looking Greninja. This hero is the inspiration for why brothers Ippei and Sanpei chose Froakie as their starter Pokémon.
- Lightning Bruiser: Despite being squat and built like a tank, Nihei's Venusaur is more than fast enough to keep up with Sanpei's Greninja.
- Spider-Sense: Both Squishy and Frogadier sense Sanpei and his Greninja before anyone else does.
- Unusually Uninteresting Sight: Squishy and Dedenne trigger a trap door in Sanpei's room, fall through a shaft, and land right in Ippei's arms. However, as ninjas, this is probably a normal occurrence for them.
- Yank the Dog's Chain: It looks like Bonnie finally found someone that accepts her proposal to hook up with Clemont...that is, until she reveals that she's using a jutsu to make herself look young. The siblings' reactions when she reveals her true appearance are priceless.
