A mannequin of a human torso adapted to retain otherwise handheld devices for simulation purposes is provided. The mannequin may have a plush shell covering filled with polymer stuffing except for a cavity therein, wherein the cavity communicates to a cavity opening defined by the shell covering. An elastic sleeve may be dimensioned and adapted to line the cavity yet protrude from the cavity opening, so that the sleeve opening is concomitant with the cavity opening. Operatively engaged along a peripheral portion of the sleeve, slightly inward for the sleeve opening, a peripheral drawstring adapted to selectively decrease the peripheral portion of the sleeve is disposed to removably retain the handheld device within the sleeve.
