Hello Carbot Season 4

Chatan continues secretly calling on the Carbots whenever an ordinary day suddenly turns into an emergency. A lost baby owl needs its mother, whales refuse to leave the shore, a Saturn probe crashes nearby, and even simple neighborhood kindness can grow into a mission for the boy and his transforming robot friends.

Other dangers are much stranger: a monster invades dreams, an uncontrollable laughing virus spreads through the city, and technology causes trouble at home. Chatan must protect the Carbots' existence while using their different abilities to solve problems that range from tiny acts of help to crises no normal rescue team could handle.
