Answer:
1. Creative.
2. Angry.
3. Dissatisfied.
Step-by-step explanation:
The myth "When Grizzlies Walked Upright" is a legendary myth about the creation of the world. This creation myth also specifies how the Indians and the grizzlies came to be.
According to the myth, the Chief of the Sky Spirits created the earth and the animals from his "giant stick". But one event where the youngest daughter was taken by the Wind Spirit and taken away from her home led to her being adopted by the grizzlies, who till that time were walking on two feet like humans. Eventually, she married one of the grizzlies and had offsprings. When the Chief of the Sky saw the offsprings that look like "strange creatures [...] A new race had been created that was not of his making!", he got furious and cursed the whole race. This was what led to the grizzlies walking on all fours and also the "strange creatures" were the first Indians.
Thus, we can describe the Chief of the Sky Spirits as someone who is a creative, but angry and dissatisfied with what his daughter had brought upon him.
