An operatic frog named Quarks is trying to sing "La donna è mobile" in Italian, but it doesn't go so well. Samson and Finchen come by to take a closer look at the noise they hear. Quarks explains to them that he really wants to sing the opera in Italian, but it's so hard. Samson asks why he has to sing in Italian. Quarks sees the point and tries to sing it in cat language. But that turns out just as bad. Samson is sure that it will work as long as they find a language that is more fitting for Quarks.
Daniel likes to sing and shows the choir he is in.
Quarks is stumped: what langauge should he sing "La donna è mobile" in? He then tries various animal languages such as dog, bird, sheep and cow, but with no luck. Finchen asks Quarks why he's trying to sing in a foreign language as he is not Italian, a cat or a dog. Quarks answers that he wants it to be special. Samson tells Quarks that he is a frog and that is special.
While shopping in a china store, Simon Soundman helps Old MacDonald find his lost animal. However, Simon's animal sounds attract animals to barge into the fragile store.
Quarks understands that he is a frog and not a cow, sheep or Italian, but how should he sing his song? Samson and Finchen suggest that he "quark" the song. However Quarks doesn't think that it's very special for a frog to be quarking. Finchen tells him that a frog that "quarks" opera is special and Samson agrees. But it turns out that Quarks has forgotten how to "quark". Finchen begins to "quark" to show Quarks how to do it and slowly Quarks begins to quark "La donna è mobile". Finchen and Samson are imprssed and Quarks is happy with the result as well, it seems he has found the right language for his concert. But before he leaves he tells Samson that his "quarking" isn't that good and that he should stick to roaring like a bear.
