"The Battle with Gravity! Catch Bubbles-kun" (重力との戦い！バブルス君をつかまえろ, Jūryoku to no Tatakai! Baburusu-kun o Tsukamaero; FUNimation "Defying Gravity"; Literally meaning "The Battle with Gravity! Catch Bubbles") is the ninteenth episode of the Dragon Ball Z anime.
As Gohan's training gets harder every day, Gokū's training with Kaiō has just begun. He has about 88 days to prepare for the Saiyans. It turns out that the monkey is not Kaiō, but it is his pet. His first task is to catch the monkey, whose name is Bubbles, but it's not going to be easy. The gravity on this tiny planet is 10 times that of Earth, making it hard for Gokū to even stand up. Just when Gokū is losing hope, he gets inspired after learning that his people withstand different fighting conditions. After three weeks, Gokū conquers the gravity and catches Bubbles.
