MacLeod's description:

Genre: Polka
Length: 1:36
Instruments: Synths
Tempo: 140

Boisterous and nearly obnoxious, this piece will lodge itself in your brain and make you think you're trapped in an arcade. The polka rhythm is quick and the melody is spastic. Right into the second minute the rhythm drops out and introduces a crazed, comedic melody that continues throughout until the abrupt end. 029
