IMDb's not a reliable source and the grave entry really only offers the individual's age (if it is indeed the same as that cited in the episode credits). All said, I don't think it's really notable unless there are some more details. And digging into it feels icky considering the subject.
Hi there! I deleted your article on the Bear dub, mainly because there wasn't much information there. If you see some of the others, they have a little more information, like channels and voice casts. If you can find that type of info, you are free to restart your article.
Hi! I'm glad you're a big Bear in the Big Blue House fan, but some of the notes you're adding either make more sense on the character pages than episode ones, or really don't fit, since we really strive to keep notes at a minimum most of the time (especially of the "This is the such and such time when such and such happens" variety).
