None, this is a children's show.

A character named "Creech" who has an outfit that contains a pink Hawaiian shirt that bares her midriff.

Just some comedic slapstick violence.

"Heck" was heard once, but it's not so bad.

In Inside Hacker, Hacker called Jackie and Digit an Earth brat and a tin witted cyberturkey. Then he said an interloping infant and a soft headed cyberturkey.

The episode "Hackerized!" can be a bit frightening to younger children.
