Gigamigo is a big ball of love, so when he noticed that Nick was suffering, he did what he could to brighten the boy's mood. Eventually he became stuck to Nick, being too loyal to ever leave his side, no matter what.
Nick view's Gigamigo as his literal guardian angel, and worships him quite often. Despite Nick viewing Giga as holy, he also realizes he is responsible in part for Giga's health, and takes care of him well.
