Yoobot

If you are doing a young learners lesson on adjectival descriptors in relation to appearances or interior decor, you might want to check this very visually appealing and smooth-running site: http://www.yoobot.co.uk/ It seems to be geared to 'teenage nutrition' issues, and does have a menu selector to feed your 'bot' character, so you could use it for food-based topics as well. Does contain a lot of high-level instructional text when getting started, so you probably want to just use segments of it related to the language areas in question.
