Cool frog; I know that at least in my horned frog's case, they spend 90% of their lives buried in dirt.. you could just tell people that you're growing tomatoes or something! I use that coco fiber stuff also for mine.
Looks like you're doing well; the crickets look calcium-dusted. Many people neglect to do this, and end up with frogs that have MBD (metabolic bone disease.) Results in deformities and death b/c of calcium deficiency.. nice frog!
