A plaster normally used to cover small cuts and grazes. When April scatters crumbs on a rubber ducky she sees in the canal below her window, a seagull pecks a hole in it, enough to propel it out from beneath the grille where it's trapped. She retrieves it from the 'Death Star' outside the Fringe Cafe, only to find that some mysterious person has covered the hole in the ducky with a band-aid so it can be reinflated. After April's finished with the ducky, she uses the band-aid to cover the enormous hole in the rubber glove she finds at VAVA.
Obtained from the rubber ducky.
