This little scratch cat head will bounce forever and ever, you never know when it'll hit the corner... It will log how long it took when it does though (: Occasionally it claims to hit all four corners in a cycle but that's because it's not perfectly precise.
Originally I wanted this to be a silly April Fools project but there were too many bugs lol Thanks to everyone who made suggestions on the help forum (: https://scratch.mit.edu/discuss/topic/752383/
