Cartoon. Boy inside robot, hiding?

Ironically, someone asked this exact question a few weeks ago and now I'm wondering the same thing. Unfortunately, I didn't comment or try to answer the question, so now I can't for the life of me find it again.

(And when I tried last week or so, Yahoo answers appears to have changed the search engine, so I wasn't able to search for it and find out how others answered it.)

ANYHOO.

Does anyone recall a cartoon (I believe it was a cartoon?) in which a boy got inside of a ... kind of like an armored robot, and the robot went amongst other robots with the boy inside, hiding him and keeping him a secret.

I remember the robot from the boy food (possible an apple?) and he 'decontaminated' it, or cleansed it, before giving it to the kid. Unfortunately, that's all I recall.

Does this ring any bells for anyone? I don't remember much, but I'm assuming this was something on either Nickelodeon or Disney sometime during the 90s.
