Cap'n Max Meddlin' (Captain Max Meddling) is a Mini medal enthusiast found in the tent in the north-west corner of Dourbridge in Dragon Quest IX: Sentinels of the Starry Skies.
He is the Dragon Quest IX version of the Medal King which is found in most games in the main Dragon Quest series.
The Cap'n gives items based on the cumulative number of medals the player has given him. This continues until the player has brought him 80 medals. Note that like other medal kings, this is not a straight trade. The player is given all the items up to the total medals collected.
After trading in 80 medals, the Cap'n will sell rare items for medals.
