HIP RABBIT HOP was one of the most influential merchandise ever released by PU4LYF (formerly known as PSYCHO.unit), back in 2009 in conjunction with the release of MA CARROTZ. Back then, there were very limited merchandises that were released by mainstream names in the Malaysian Tamil music community. Being a relatively new name and with a maiden album, PSYCHO.unit managed to break odds and sold over 3,500 pieces of the tee during that time, which is considered a runaway success for a relatively newcomer.
