(sorry if "baloobius" in the title is misspelled - i've never seen it written anywhere else but unofficial sources!) so we know for certain that matt does not have the tuft on the end of his tail. like that is very gone. however, when you watch the episodes where he is shown as a younger fraggle, it's there. we - i, maybe - know why it's gone (with reference to character design and symbolism, you can ask about that! I Love To Explain It), but do we know how he lost it? did it fall off? did it get detached? did it just grow out?
