Creating a select character effect like Crossy Road?

Hi, does anybody know how to achieve this select character effect (lots of character can be seen at once, but only the middle one is highlighted by becoming bigger) ?

The crossy road’s character select screen is attached below.

thank you

Something like this play around with the numbers to get size u want.
Haven’t messed with scale myself so might not work.
transform.localScale += new Vector3(2F, 2f, 2f);
To select the character OnMouseOver or OnMouseDown

Void OnMouseDown(){
transform.localScale += new Vector3(2F, 2f, 2f);
The highlight u prolly need a shader there's a free asset called cactus pack ?in the store that has a shader  that works well.

Of course if its 3D then could just be a case of moving the selected character forward towards the camera.

In my case it’s 2D Sprite
