After burnt toast ruins their sleepover, James and Max create "Toasty," a sentient toaster — but they have wildly different ideas on how to raise him.

James' mom turns him into a smartphone to see if he’s responsible enough to have one. But staying damage-free proves harder than he expected.

When James accidentally saves Mr. McFly from a school bully, the troublemaker takes his revenge by entering James's body to wreak havoc from within.

A teenage Toasty returns and starts acting out — in a big way. With the future at stake, James, Max and Echo must deal with him once and for all.
