Excitable Edgar? Only £15 from John Lewis (and maybe Waitrose, depending on branch). Personally, it's the cover version of REO Speedwagons song by Dan Smith that I like!
I like it Nellie because it's catchy and they move well to the music. I think John Lewis's ads are all the same now, trying for the awww vote, but I accept they are popular.
A well known parental website has been having complaints about it! Apparently his behaviour at the start demonstrates a lack of understanding of the consequences of his actions and is upsetting to the parents of children who have the inevitable issues and behave like this!!
