April and Irma visiting Pfeiffer's Jewels
Pfeiffer's Jewels is a jewellery shop in New York City. It appears in the "Four Musketurtles" episode of the 1987 TV series, where it's attacked by Bebop and Rocksteady robbing it on the Star of Brazil diamond, causing April to call the Turtles to show up. During the fight, Leonardo is knocked unconscious, waking up thinking he's d'Artagnan from Alexandre Duma's The Three Musketeers.[1]
