Mind Eraser

The Mind Eraser was an invention in Talking Tom and Friends. It was created by Ben in A Secret Worth Keeping: Part Three, before being destroyed in Forgotten Kiss.

Description
The Mind Eraser was a pen-shaped activated with a press of the red button on its end. Once pressed, the Mind Eraser emits a bright red light. Those who see the light quickly lose their short-term memories. The time range of erased memories range from a few minutes to two full days.

Ben has also created a pair of protector shades that prevents the wearer from being affected when looking at the light; however, normal sunglasses also provide adequate protection.

In Forgotten Kiss, due to changes made by the CEO, the Mind Eraser now looks less like a pen. It now has three antennae made of tungsten, and a cone-shaped device on its end.

A Secret Worth Keeping: Part Two
When Angela exposes her secret crush on Tom, she asks Ben if he could build a machine to erase his memory so that Ben could forget the secret. The idea for the Mind Eraser was first conceptualized in this episode.

A Secret Worth Keeping: Part Three
Ben had successfully created the invention and used it to erase his memory. This had backfired as it accidentally affected Hank's memory when he was meant to inform Angela about Tom and Ben Enterprises new success with the CEO in a tech conference.

Eventually, Tom had thought Ben betrayed his trust when he mistook Angela removing hot cheese from Ben as dancing and kiss him. Out of rage, he sells the company to random people in the conference. Ben and Angela explain he had seen it wrong and realize that the company is gone. Angela comes up with the plan of using the mind eraser to make everyone forget that he had sold the company and regains it.

After that, Tom and Angela had admitted their feelings for each other and are about to kiss when Hank sees the mind eraser, he is curious and presses the button erasing all of their memories, except for Ginger who was wearing sunglasses.

Forgotten Kiss
It was revealed that the CEO had kept the mind eraser and was modifying it to erase the entire world's memory. Tom fights with him and accidentally erases the CEO's goldfish, Goldie's, memories which infuriates the CEO. Tom takes the eraser back and then destroys it.
