>>9382153Based on that theory, I assume that is also why a Ga-Matoran character wearing a Kaukau wasn't introduced until year 2 with Hahli. Perhaps they couldn't get the color of her mask right in '01 or producing a transparent mask for a free toy in large quantities would have thrown the Happy Meal budget out of balance.
All other Happy Meal Tohunga had masks corresponding to their Toa, except Macku. Each village in '01 also had two "sets" of named Tohunga, the six from the Happy Meals (Macku, Jaller, Hewkii, Kongu, Onepu, Matoro) and six secondary ones (Kotu, Kapura, Hafu, Tamaru, Taipu, Kopeke). No other Tohunga was given a name back then, even Takua was nameless until the very end of '01. Ga-Koro's secondary named Tohunga was Kotu who almost never appeared in any media and was sidelined when Hahli appeared. Hahli even got a set in '01 while Kotu didn't. The plot of MNOG II was also about this newcomer Ga-Matoran with a lighter-blue Kaukau who we never saw in '01 suddenly taking over Kotu's place.
So I imagine the plan for a Kaukau-wearing blue Tohunga model already existed in '01, but they just couldn't produce it, and so they gave other types of masks to Macku and Kotu. By the time they did find a way to produce the Kaukau in an altered blue color for the upcoming '03 line, they hastily invented Hahli, pushed her into the story and shoved Kotu aside.
