Thor Signaller
From Jenny Everywhere Wiki
Thor Signallers were grenades specifically adapted by Dynamite Thor to make an even louder noise. He hoped that he could distribute them to his friends, who could then use them to call him from afar if they needed his help. Naturally, Jenny Over-There was less than enthused about the idea when he presented it to her on June 18th, 2022. (PROSE: Workplace Reunion) Later, when seeing Glenda off before going on a patrol in Knighton, Thor left her a similar “signalling device”, a “small, dark-green object that appeared to be a grenade to the untrained eye… because it was one”.
