Please make sure you don't remove <!-- only put in documented cases where DreamWorks said "we based this character on" --> from articles, like you did here. Doing so is against the guidelines. The guidelines are that no unsourced inspiration may be allowed to be added to pages. Also it means that no tags that tell users not to do those things should be removed either, since doing so would undermine the guidelines.
Nieve, the reason for this is that people have been going overboard with what they're putting in the Infobox, to the point where it's being abused. The inspirations were more along the lines of "well, it kind of reminds me of this, so it must have been inspired by it".
It's part of trying to clean this place up and get people to focus on putting their efforts into talking about characters and the stories they appear in, rather than resorting to lists in the Infobox, categories and a few other places.
