Nice first quiz! I’ve only read these once, so it was challenging. (8 minutes is a lot of time for only a few answers. Usually these sorts of quizzes will have 4-5 minutes of time, or less. But you can keep the time like this if you’d like.)
According to the sources I found, the mother and father are named Susan and Jon. Also, because of you putting “(s)” at the end of the snail answer, “s” is accepted as an answer. Please fix this.
