Episode 101 is a filler episode that just so happened to be adapted from an omake. I think it's more a similar nature to the Shippuden omake that they used to put at the end of episodes (it was much shorter in the manga and only 3 pages). But anyway, it still fits in perfectly between episode 100 and 102.
