„I feel there is sensuality... eroticism in the primary things that move, like animals and insects. Being able to inspire the movement to still images... gives me the joy of the creator that breathes life into things that do not have life. The movement must be sufficiently round and sweet... so express its eroticism. In creating cartoons I always think of an ideal, but... half the finish to doubt the rightness of what I'm doing. So I put all my expectations always work next. * * [... ] I often say jokingly that comics are my true wife and that the cartoons are my lover. The fact that I am fully dedicated to animation, my lover... is because it allows me to express in a sublime... the interesting metamorphosis of a changing body. For me, the greatest fun, no doubt, lies in the draw and give movement to change processes. Always look in my cartons this metamorphosis.“
