Alright, this episode may not be one of the really good episodes, but it's far better than this sheep-disaster
Especially Bigwig is great in this episode (Who would have thought it with that title

?)
Also Tassel is introduced in this episode (at least she and her squirrel-friends will help Watership Down in the third season). Generally, her tree adds a nice location to the series.
The problem, I have with this episode: It's right before the season-finale. On DVD, we have the piece of luck, that this episode is placed within the third season. But seeing it in order of the series, it's simply prolonging the season.
