With Dunsparce I actually want to make like a hoodie that is basically Dunsparce. The back has the stripes while the front is just plane yellow. Also either sew on plush wings onto it and the hood part has Dunsparce's eyes on it. And I thought maybe make a small face mask to represent its mouth.
Ah ok...well one I'd suggest that might be easier is either...like stated before monotype. Since it is just using one type of pokemon like only using grass type pokemon or bug. Another might be a random pokemon challenge where you randomize your team. So essentially like on pokemon showdown and the random battles.
It would depend on the challenge. Cause some might be more detailed with requirements and all that while others are just loose and you can do whatever as long as it fits. So it is more of what you'd be interested in. But in my opinion they are fun just depends on what game and how difficult the challenge might be to "set up".
