Well here's mine: Beach Turtle!

"Sometimes you just need to relax in the summer, the Beach Turtle can bring it to you! Equipped with an isolated island with a Coconut tree, and a large umbrella!"

(More photos in my photostream! Including one with a beachball )

And yes, it does fit with the umbrella on an 8x8.

Tenticle Turtle by Sir Brickalot, on Flickr

The slenderness of the Tenticle Turtle doesn't exactly make it stealth, but it does allow for its crystal tractor beam to attract objects from high above.
