Having become the underdog, Goku swallows a senzu bean, but he shows absolutely no signs of recovering. And with good reason, since he was suffering the effects of a heart illness. Piccolo steps in to help Goku, but is obstructed by No. 20. Just as things look grim, Vegeta shows up and rescues Goku. However, Piccolo has misgivings about Vegeta being able to defeat No. 19.
