Driftwood Jellyfish Sheets

The Driftwood Jellyfish Sheets is an item that appears in Mario & Luigi: Dream Team, and one of the five Ultibed parts. It is a collection of jellyfish-texture bedsheets found in Driftwood Shore. Mario and Luigi find it in a room hidden behind a suspicious door after they receive an Old Lithograph from Broque Madame. Before they can retrieve it, a trio of Fly Guy R thieves steal it. The Bros. must replay Mole Hunt to obtain whereabouts from the Mole Hunt Proprietor, then head to Pi'illo Blimport. Once they defeat the Fly Guys R in battle, the Bros. can collect the sheets.

Hint

 * "The deepskyblue, as the name implies, are said to be on deepskyblue. Who might know about them?"
