Gumshoos shares many similarities to its previous evolution. Its main fur is brown, but the top and underside are yellow in color. Gumshoos has three, black toes on either paw. Unlike its pre-evolution, Gumshoos is now in the bipedal position, and is much larger in general. It has large white eyes with horizontally-slitted pupils and it has spikes on its fur that resembles a detective's trenchcoat collar.
Gumshoos deploy the opposite strategy from Yungoos when hunting. Instead of prowling around for its prey, Gumshoos stakes out its prey's usual routes and waits for it come by. It's known to be patient and persistent.
Gumshoos continues the trend of a common Normal-type mammalian Pokémon in a two-stage evolution and placed early on in the Pokédex list.
Gumshoos has horizontally-slitted pupils, similar to real-life mongooses.
Upon its reveal Gumshoos drew comparisons to then presidential candidate Donald Trump due to its similar-looking hairstyle which quickly became an internet meme. However, the Pokémon Company has denied any intentional connection.
Further fuel for such jokes included the fact that Gumshoos was brought to Alola to deal with the Alolan Rattata (which resembles a stereotypical Mexican bandit with a mustache) and that its ability makes it strong against Pokemon coming in (compared to Trump's motions against immigrants).
Gumshoos is based on a mongoose and a detective.
Gumshoos is a combination of "gum shoe" (another name for a detective), and "mongoose".
