Shinx isn't available as partner pokémon in the Ranger games.
(even if befriended pokémon can be asked favors endlessly pretty much like partners...)
Also, shinx doesn't have the electric cheek pouches.
Clauncher?Pffft, this isn't "hug or kill".
Okay, hint : this one involves transportation in a long-forgotten sidegame
(however there's an other more obvious difference you might have already noticed)
Staraptor, dodrio & floatzel
EDIT: Guys, please help keeping this topic alive! Thank you very much indeed!
EDIT serie2: Need hints? Remember : the possible answers can be multiple...
for instance, shinx doesn't have the electric cheek pouches pachirisu and minun have,
but minun is the only one from a different generation.
