Hope this helps! Alas I couldn’t find a list of available bitmoji search terms without installing bitmoji app.
Bitmoji Search Tip: If you’re having trouble finding a standing Bitmoji without additional text or art, type “pose” into the Bitmoji search bar! This gives students a single source to reference each day without having to scroll through the Stream or Classwork page. Open the Bitmoji app and tap the Settings icon (shaped like a gear) at the top right corner of the screen. Time: It took me about 4-5 hours to create my Bitmoji Library from start to finish.
