Testing theories. For Science! by request (and because the kraken are terribly bored) draw a box with tape on the floor. wait. .
Top Left is after application of tape. possible complication: they saw me lay down the tape.
Top right is Jack returning to the bag that moments before had been dead center in the square with Jack inside. play happened, bag moved. lather rinse repeat.
Bottom image is Jack bs k in the bag and Charlie enjoying this fact. Findings? cats like bags. cats don't care about human plots and plans.
