S1·E6 – The Worm in Big's Apple

Small wants the glorious apple that's hanging from the tree, even though Big tells him it's not yet ripe... But Small looks so sad that Big puts friendship above his knowledge of apples and picks the fruit. But 'Yuck! That's not an apple, that's a lemon!' is Small's reaction to the first bite. Big takes a bite himself to see if it really is that sour - and recoils with horror when a voice speaks to him from inside his mouth! He has swallowed something that lived in the apple! Small reaches in to free the trapped creature - who turns out to be a sassy but warm-hearted worm. She doesn't have a name but suggest they call her Twiba: The Worm In Big's Apple. And now Big and Small have a new friend out in the garden. Small asks Big to pick the juiciest apple on the tree - but the apple is home to a talkative green worm!
