"A follow-up to the N-ZAP '85 , now with a sleek orange paint job. The sub and special have changed too, but its populatiry remains high as ever."
Sheldon's quote: "Ah yes, the N-ZAP '89 . This is quite simply an N-ZAP '85 that was redesigned for... legal reasons. It includes a Sprinkler to rapidly increase your turf, allowing you to fire off remarkably fast Inkstrikes! This set is excellent at striking where the foe least expects it. Good for lone wolves!"
Its appearance resembles the re-released NES Zapper.
Sheldon's comment that it was redesigned "for... legal reasons" is a reference to the re-released Zapper's own history. A change in toy gun regulations required all toy weapons resembling firearms (realistic or not) to have an orange tip or barrel. This was done to avoid toys being mistaken for real ones from a distance.
It's commonly thought that this change was part of a ruling specific to the Zapper, or that it was voluntarily changed by Nintendo for this reason. However, it is more likely due to laws affecting all similar toy guns.
