Mickey Mouse and his pals Minnie, Donald, Daisy, Pluto, Goofy, and Pete invite toddlers and preschoolers to join them in Mickey's clubhouse for some playtime fun and adventure that emphasizes teamwork and aides in the development of logic and math skills.   In "Mickey's Treat," Mickey and his pals are dressing up in costumes to attend Big Pete's Halloween party--the only catch is they have to make their way along a candy corn path and through the foggy woods to get to the tower before the moon is full.  Only by working together and using the appropriate "mousketools" can the group make it to Pete's party on time.  "Goofy the Great" finds magician Goofy desperately in need of some practice before a big magic show.  Luckily, he can count on Mickey and his friends for lots of encouragement and some counting and patterning help.  In "Doctor Daisy, M.D.," Daisy works toward earning her pretend doctor sticker by seeing an office full of willing patients and curing their ills with a little help from her friends and some handy mousketools.   Also included is a bonus episode "Little Einstein's Halloween" in which the Little Einsteins' preparations for their Halloween party take them to castles around the world.  The episode features art by the Lumbourg brothers and music by Edvard Grieg. (Ages 2 and older)--Tami Horiuchi
