Codename: Kids Next Door (Seasons 1–6)

Codename: Kids Next Door (2002) is a Cartoon Network animated series you can watch online on iFILM. Six seasons follow five ten-year-olds who operate a covert team from a treehouse headquarters, taking numbers instead of names — Operatives 1 through 5 — and treating every parental decree like an act of war.

The KND's enemies range from homework-obsessed teachers to a shadowy adult organization with global reach. Their weapons are built from ice cream, cardboard and duct tape. Somehow it all works. Ben Diskin voices both Numbuh 1 and Numbuh 2; Kree Summer plays Numbuh 5, the squad's coolest head under pressure. The humor runs on spy-genre parody, but underneath it sits a genuine story about loyalty and the very specific fear of growing up.

Each episode functions as a self-contained mission, which makes the show easy to pick up and hard to put down. Stream all seasons of Codename: Kids Next Door online on iFILM.
