He first makes his appearance when The Wise Little Hen asks him to help plant some corn so that her chicks may be fed. She asks Peter if he'll help her plant corn, but sadly Peter complains of having a belly ache and snorts off.
The Hen decides to plant the corn herself. As soon as the corn had grown, the Hen asks Peter again if he'll help her. He and Donald Duck fake belly aches again and went into a club house they owned. Peter banged the door so hard the wall broke, but the Pig and the Duck were shaking hands without noticing the wall at all. The Hen saw through their trick and agreed with her chicks to not let them eat any corn when it's done.
When the corn was finished, the Hen decided to ask Peter and Donald if they wanted any. They agreed and came rushing over to grab the basket full of corn. They fought over it but then decided to dig in. To their surprise, it was castor oil for belly aches! The Hen and the chicks enjoyed their meal, while Peter and Donald kicked each other in the rear for the rest of the day.
Peter Pig appears with the rest of the band, after just having played music from Zampa. He and the band next begin Rossini's William Tell overture. Peter Pig soon starts to disturb Mickey Mouse from conducting with his vibrato trumpet playing.
Then, Peter and the rest of the band start to play along to Donald Duck's flute rendition of "Turkey in the Straw" instead of the finale to William Tell. After Donald is kicked off the stage, Peter Pig and the rest of the band sees Mickey's swatting of a bee as a cue.
The band soon comes to the "storm" segment of the overture, which summons a tornado. It sucks up Peter Pig and the band members, but he and the band are now used to distractions and continue to play within the tornado. The band members are thrown off course as the tornado passes, causing Peter Pig to lose his clothes one at a time to tree branches and land into a barrel completely naked and the others to be stuck in a tree, and the overture comes to its conclusion. By this time the only remaining audience member is Donald Duck, who applauds enthusiastically. He then produces one last flute and plays "Turkey in the Straw" again, but Peter Pig throws his instrument, along with the others, at him.
