I was thinking of doing some kind of Disney character and altering it somehow. I thought of Olaf and maybe changing his carrot nose to a different food like a tomato or strawberry. Also, change his arms to a different type tree or something like that.

I think that this is such a fun idea. I think it might be cool if you made Olaf in different seasons I think it would be really fun to see that and it would really bring your idea to life.
That sounds like a very fun idea, maybe you could make the bottoms of all the objects and ports where they will be put into Olaf the same design so you can mix and match different parts of his body.
I agree with Lauren, I think it would be cool if you could customize Olaf with different parts! You could also customize the buttons with sunflowers or lemon slices (or really anything round)
This idea is cool! I think changing the sticks on his head to be a small bush could be fun.
I like the idea of switching up his nose and arms. I think it might also be cool to make him melting in summer too.
I think it would be really cool if you used something like an umbrella or something related to other seasons to give him a different feel.
