The animation in this French film is comparable to that of Novembre [November]. An unlikely friendship between a tadpole and caterpillar progresses as each grows up into two very different beings: a frog and a butterfly. The film centres the classic theme of metamorphosis and the issues of sameness and difference that can arise from this, with an interesting twist when the butterfly goes missing. Told in a stylish visual animation style, this short tale is a good-humoured means to consider friendship and solidarity in a changing world of unfixed identities.
