Yungoos and Gumshoos
As usual, the early bird comes alongside the low-level normal-type mammal of the region, and this time, it's a cool little mongoose that absolutely does not look like any real person at all and was apparently brought to Alola to deal with its Rattata and Raticate problem!
Yungoos evolves into Gumshoos, resembling a grizzled detective in a newsboy hat and also not at all like anything or anyone else worth mentioning in the presence of something as pure and good as Pocket Monsters.
What IS worth mentioning is that this whole Yungoos/Rattata situation is completely real. Mongooses actually were introduced to Hawaii to deal with also-invasive rats, but unfortunately, the rats were nocturnal and the mongooses diurnal - something actually mentioned in this line's dex entries. It's why they have a signature ability called "stakeout" and look like "detectives," while Alolan Rattata and Raticate look more like little burglars. Unfortunately, Gumshoos is said to fall asleep on its "stakeouts" and seldom actually gets ahold of Rattata prey.

It's great to see so much thought put into one of these normal-type furballs.
