In addition to being confused by this translation, what's with all the pictures of Kotone in a team rocket uniform?

Theres a part where she dress like one in the new versions of the game (or manga, anime, dunno) and silver discover her If I had to take a wild guess

in the new game you can disguise yourself as a rocket for a short while. Silver is the one that reveals you.

Is it just me or do her arms seem a little on the stubby side?

The arms are an error.
