"Gyorocchi Theme - Patapon" is a high quality rip of "Gyorocchi Theme" from Patapon.
The rip is a mashup of "PONPONPON" by Kyary Pamyu Pamyu with the battle sounds from Patapon. "PONPONPON" provides the vocals and instrumental while Patapon battle cries provide the melody. Samples from "Gyorocchi Theme" also appear in the rip.
The main reason for the mashup is that the battle cries of the Patapon Tribe from Patapon are variations of "Pata-pata-pata-PON!" and "PONPONPON" contains one of those syllables.
