This is a mug shaped like a Tiki wearing a diving helmet. It has a grayish silver & brown glaze combination. The helmet is covered with coral mass growths and has a small octopus clinging to the reverse.

From Tiki Farm:

"Harkening back to 2011, we resurrected this very popular and clever Tiki mug design by Flounder and decided to offer it in two different color-ways to help appease the masses!

Aqua Tiki is the first deep diver Tiki mug of its kind and inspired many similar variations in the Tiki mug market. Shaped like a detailed vintage-style diving helmet the mug features a tiki inside (perhaps gasping for air!) and an octopus on the backside looking for a way in!

Aqua Tiki features a dark wrought iron exterior with an accented brown lustre tiki. Aqua Tiki stands 5 inches tall and holds 18 ounces of your favorite libation.

Hand painted by Tikito and the USA Tiki Farm team, this is your chance to get this collectible mug! Only 250 made in each color-way!"
