It's implied that Zak and Cloe are in love in several episodes.

Very mild (attacks with balls, fallings from air, destructions, explosions, etc.) Lon and Sidmodius are brutes.

In the Spanish dub, there is a episode called Move the A**.

Ocassional uses of "heck", "damn", "stupid" and some other mild curse words.

Some emotive moments.

Season 2 is darker
