Specific I need help to unblur a photo

[suzykesbi]

Hello gurus,

I have a picture that I'd like to unblur. It is a bitmoji of my former principal that needs to be stretched out on a poster for our high school reunion, but since the bitmoji is small, the picture is all blurry and pixelated when stretched to 45cm (length) . Are you guys able to unpixelate it with photoshop? Ps: we have his permission to use his bitmoji.

Thanks
