Following info comes from Kamiya...

- "don't be worried, it's a 100% pure action game"
- Unite Morph was inspired by a picture book he saw when he was a kid
- this book was called "Swimmy", in which lots of little fishies come together to form a big strong fish
- Nintendo didn't like the idea of an all-star cast of Nintendo characters
- design philosophy is "Crash and Build", since working off a blueprint doesn't work for him
- Wonder-Giant is one character design that didn't make it into the final game
- Kamiya would make Wonderful 101 posters to help excite the staff and push them forward
- one unite morph has a bazooka blasting guys at a t-Rex
- one portion had characters come together to form a bridge
- Nintendo concept art of Peach, Luigi & Yoshi as the bridge with Mario walking over them
- this is when Nintendo decided against the idea
- the Unite Morph was not originally a drawing a mechanic, but was triggered by something else.
- conversation system was introduced in the second prototype
- trigger for Unite Morph was originally based on selecting icons
- character designs, when finished, were placed on a board for all the devs to see
