Zim appeared out of nowhere, seemed to hang for a moment in mid-air and then flops down to the ground gracelessly, only to land on his face with an audible THUD. He remained there for a set of moments before his left hand twitched, followed by his right arm and he somehow picked himself back up from the floor.

"HEY! What is this?!" the irken complained loudly and marched around himself in a little circle "I didn't chose to be here!!"

No. He didn't notice the human sitting just over there. It was just a human after all.
