During the Party:
Divide your guests into two teams. Flip a coin to see which team will go first. Start describing one of the Pooh characters to the first team, one characteristic at a time. Keep giving descriptions until the team guesses the correct character. Write down the number of clues it takes for the team to guess the character, then move to the next team. Describe five characters to each team. At the end of the game, add up the amount of points each team accumulated. The team with the least points wins!
For a non-competitive game, have all guests call out the character name as soon as the know it, and work together to figure out the more difficult ones.
