Elliot Six and Eraser fonts
The idea of this template is to emulate a children’s book. It’s low effort to produce a large amount of slides, as you only need to find one hand-drawn image from IconFinder per slide. Otherwise, the typography is enough to make it eye-catching.
You can get away with softer browns and oranges for the backgrounds of this style of slide
