"Superfast Jellyfish" is the second single released from British alternative band Gorillaz' third studio album, Plastic Beach. The single was released on 9 May 2010.
The song features vocals from Gruff Rhys, lead singer of Super Furry Animals, and De La Soul, who were previously featured on "Feel Good Inc.". The song contains samples from a 1986 commercial for Swanson's microwave "Great Starts Breakfasts". Band member Murdoc Niccals stated the following about "Superfast Jellyfish" in a track by track commentary:
"When you think about Gorillaz, it makes sense to have a Super Furry Animal on there, doesn’t it? I’ve always loved them, so I sent a jet over to pick Gruff up and take him over here."
The track premiered on BBC Radio 1's Zane Lowe show on 25 February 2010. About an hour later, it was uploaded to the official Gorillaz YouTube channel. The first official remix of the track, by Unicorn Kid, was premiered on BBC Radio 1's Zane Lowe show on 12 April 2010. On 27 April 2010, the group performed the song live on "Later... with Jools Holland."
played live in 1989
Mr. Trouble never hangs around
When he hears this mighty sound...
"Here I come to save the day!"
That means that Mighty Mouse is on the way.
Yessir when there is a wrong to right
Mighty Mouse will join the fight
On the sea or on the land
He gets the situation well in hand
So though we are in danger
We never despair
Cause we know that where there's danger
He is there!
He is there!
On the land!
On the sea!
In the air!
We're not worryin' at all
We're just listenin' for his call
"Here I come to save the day!"
