Calvin Schwa has a unique problem - nobody knows he is there. When Antsy and his friends discover this, they decide to run experiments to see just how 'invisible' the Schwa is. They ask him to perform all sorts of daring tasks, including standing in the boys' bathroom in a day-glow orange sombrero and cat costume, singing 'God Bless America' at the top of his voice. When the Schwa is dared to break into the apartments of an elderly, crotchety restaurant owner, the boys get quite a surprise-the Schwa is seen! This leads Antsy and the Schwa into a new and exciting experience.
