[sh-] Shrek is in the [3] basement of the [-_] house, where he is being taught 史 history by a walking broom that has a 口 mouth. Of course, the only noises it makes are weird cracking wood noises and shuffling hay, but it is going over the 史 history of the walking brooms, presumably. Shrek sits with a concentrated face, as if he could possibly understand the nuances of walking broom 史 history.
