The Sandown Clown, also referred to as: All-Colours Sam, was a strange being encountered by two young children vacationing at Lake Common, Sandown, Isle of Wight (UK) in May of 1973. Following a sound like an ambulance siren, the children wandered across a wooden footbridge over a stream, & met a curious, unidentifiable being that has been described as "a cross between a clown, a robot, and an alien".

It was a shy, but friendly being, & spoke kindly to the children for almost half-an-hour before they returned to their parents. It seemingly vanished after the encounter, & has never been seen again.

Despite standing 7ft tall, the Sandown Clown had more or less normal human proportions: 2 arms, 2 legs, & a round head with identifiable facial features. However: the being's head was described as being too large for its otherwise thin frame, & shaped like a nearly perfect sphere.

Its skin was very white, & had the consistency of paper, while its hands & feet possessed only three digits each, & its face seemed to have been crudely painted onto the surface of its head: two blue triangles seemingly represented eyes, while a flat brown rectangle served for a nose, & its mouth had thin yellow lips shaped like an oval, which did not move at all when it spoke or ate.

Its hair hung down beneath its hat in sparse, frizzled, reddish-brown strands, & two antennae stuck out from the sides of its head, while more slat-like antennae extended from its wrists & ankles. It seemed to be wearing some type of clown costume which consisted of a tall pointed hat with a black knob/bobble at the top, & a high-collared suit of red & green with long, frilly trousers & sleeves, to which the hat was at first attached, but was later removed by the being to show its white & apparently balding scalp. It wore dark blue gloves, but its feet were bare.

It was also carrying a microphone or tannoy system, through which it spoke, & which is believed to be the source of the ambulance-like siren heard by the children.
