Update: I fixed Baby Mario's shoes.

This is the group image artwork of the Mario & Luigi: Partners In Time remake but it has the Japanese logo in it, it features a much more expressive Luigi and Baby Luigi in the artwork similar to the Bowser's Inside Story remake's boxart where Luigi and even Starlow were more expressive than the original Bowser's Inside Story's boxart. It also features a Koopa Troopa pilot which he's upside down just like how Bowser Jr and the other two Koopalings were upside down in the boxart of the Bowser's Inside Story remake.
