Pichu goes on a cool adventure on his own to this wonderful island he would go swimming in this cool safe ocean where he had it all to himself but he feels his diaper butt all gurgly and bubbly so he would panic and think of what to do so he goes underwater and swims very deep bellow and would sit his diapered butt down inside the sand and would hold it in as much as he can but while he does that he doesnt notice that his diaper would overflow with water so it gets very heavy for him to move
