WoWHead user Haldhur found a Genie on an island off of Talador's coast that appears to be a tribute to Williams’ role in Aladdin.
Robin’s genie character is summoned by rubbing an Ever-Burning Lamp. He recites two lines from that film: "Infinite cosmic power!" and "itty bitty living space".
Nearby is a large broken egg – a possible tribute to the character Mork from Mork & Mindy – as well as some stuffed animals and tanks, suggesting tribute to Toys.
WoWHead previously found versions of Robin dressed like Mork and Mrs Doubtfire in the game’s code, so those could make an appearance as well.
Blizzard agreed to include Williams in the popular MMO after being petitioned by fans.
