In Cow Cat Jump the protagonist is Oscar, a loveable cat whose fur resembles the Holstein cow pattern (that's where the name comes from too). His friends are sick and the only way to cure them is by finding a flower with holistic properties, the only problem being that it's only found around a dangerous volcano. Oscar has to dodge invincible enemies (such as dogs and flying fireballs) but it can destroy others by jumping on them.
