Straw

Straw is a heart-shaped straw which Imounu used to steal Bowser's HP in Mario & Luigi: Bowser's Inside Story. Straw has no physical attacks, but is merely used by Imounu to steal Bowser's HP and recover her own. It is pink in colour, and seems to be a part of Imounu, as the straw can be summoned out of Imounu's mouth at any time, instead of needing to be picked up. Whenever Straw appears, a tribe of Bifizu People usually appear to defend Imounu, and attempt to distract the Mario Bros., whilst Imounu recovers HP. Straw does not need to be killed, but can be if one wishes to prevent Imounu from regaining HP.
