This is a mug shaped like a snarling ape head wearing a necklace of alternating yellow diamond and round red beads.
From the Lost Temple Traders website:
"On our most recent expedition, we were met with an ominous warning from the locals. 'Kunga Kong is coming!' Could it be? The beast of legend would finally make an appearance? Kunga Kong is a hand-made collaboration between Lost Temple Traders, Tickled Tiki, and sculptor Dale Silva. Limited to 150 pieces, it measures 6.5 inches tall and holds 21 oz. of your favorite beverage."
