Handy Manny/WMG

Mr. Lopart's shop is cursed.
Which explains how Lopart manages to break everything, the curse of the shop is following him around. And in one episode where Manny had to watch the shop, all the machines and a pinata Lopart was working on for a client broke anyways, so Manny and the tools had to fix everything.

In the same vein, there will be some kind of spinoff that involves the tools, but with another member of Manny's famiy taking over because of another thing that Manny had to take care of.
With Manny out of the picture for a while, someone needs to watch the tools, so a family member will have to do it until he returns.

The nice thing about this idea is, the series of series could in theory run forever -- there would always be someone to run the shop.
