It seems that the beauty of muppets is bought by IQ. Some muppets are not very good at managing themselves. They sleep all day long, eat and sleep. They are easy to get fat, and occasionally they rush to tear down their homes. Their sleeping posture is very strange. They look stupid every day and often catch a cold and cough. The key point is that muppets with off-line IQ often don't bury shit, indigestion, constipation and so on. Therefore, the shovel officer who keeps muppets suggested preparing some active probiotics.
