GHMR-002 and GHMR-004 are likely not to exist. Considering Shine ~For High Time~ is labelled GHMR-003, it is possible that its earlier counterpart Water ~For Relaxing Time~ was once planned to be marked GHMR-002, although this is only speculated. The true reason for the absences of these two numbers is unknown. On the other hand, there have been items sold through Grasshopper's online store which sold out and were cleared from the database before their GHMR imprint could be recorded, such as the colors "Travis Touchdown Mug Shot Tee" was originally manufactured in, and the "Hell Ride" T-shirt, as well as each of its colored variants. Flower, Sun, and Rain: Murder and Mystery in Paradise T-shirts are also known to have once been produced, as well.
