There is nowhere specified if the applications work one with each other, but the Cricut Explore One allows you to import image and fonts which means it's possible to export the content from Funtime (using a standard image format) to Cricut. If you have both applications installed, open Cricut, then go to File > Import or File > Open. You should get an overview about the files that can be imported, then use Funtime to save the file to a supported format and that's it.
