Spice and Vinegar in “Unfinished Business”

[about Piccolo] His Namekian body is having a strong reaction to the venom.

Vinegar

Too bad. Lets put him out of his misery.

Vinegar, stop. We mustn't kill poor Piccolo. Without him, we won't be able to use the dragonballs.

Vinegar

Do I get to kill him later then?

'fraid not. Why should we hurt a friend? If you're bitten by someone who's been infected by the black water mist, you become just like them. Piccolo's one of us. Yes, wake up. You're part of the family now.
