Mew, pokemon #151, is so rare that it is still said to be a mirage by many pokemon masters.  Only a few people have seen it world wide (er, including everyone who's seen the first pokemon movie *grin*).  

From a "mom's perspective", Mew is a tiny little psychic pokemon that looks a bit like a siamese cat with really big eyes.

Mew is made with a toilet paper tube, a printer, a piece of paper, some crayons, scissors and glue.  I always prefer to use a heavy paper (like construction paper), but it isn't necessary.
