No idea why Exploud is on the list. Or Electivire, Gigalith and Magmortar. Being a monster is too vague. If they fit Halloween then Rhyperior does as well.
A couple of suggestions:
- Lunatone is related to night (this is why Solrock isn't on the list despite being equally mysterious)
- Victreebel can be categorized as a "Lure"
