Going through my Google Drive resources folder I found this Google Slides with 5 challenges for Google Apps. The image for Google Forms was still green (instead of purple) so you know it was needing updating.
These challenges would be for those newer to G Suite. Add fonts to Google Docs. In Google Slides change the background image. One of my favorite things to do in Google Sheets is to quickly number from 1 to 100. In Google Forms you can add an image to a question by hovering over the question title and allowing the image icon to show up. The magic sauce to drawing in Google Drawings is to hold down the Shift key. Create perfect circles and straight lines.
