I really need this font soon for a school presentation. This is the perfect looking font for the theme of the presentation. I need the font name that says "Episode 100 Tour"

It couldn't be that font. Mrs.Monster has holes in the letters. The font in the thumbnail does not.

it is, holes were filled

How is that possible? Is there a software people use?

probably the same software people used to create what you call "PythonMC Thumbnail", something like Photoshop, Gimp,...
