This is a mug shaped like a Moai with a large bowl-like red top knot encircled with Bird Man petroglyphs and labeled for the Aku Aku.
From the Aku Aku Tiki Bar:
"Designed by Flounder and made by Munktiki Imports. Pukao is the second mug Flounder has done for Aku Aku -- he has also did our first mug the Tiger Mug. Limited Edition of 500."
