Dragon Ball Z - episode 88 - 23 Apr, 1991

As the fight continues, Goku attacks from underwater upon realizing that Frieza can't sense power levels. As Goku seems to be in control, Frieza uses his mind to use rocks to attack Goku so he can trap him in an energy ball that will explode if it touches anything but Frieza, and it doesn't look good for Goku. Although Frieza launches the energy ball towards Namek when he grows bored, Goku manages to break free at the last possible moment. (Source: Wikipedia)
