Here's yet one possible way that combined babysitting can go awry. Bert and Algie are Zoe's younger cousin and they were visiting just as Sammy and Remi were spending the day at the Pennyworth's home.

EDIT - Welp, we've finally got the colored version done and added it here. We're not yet sure if we'll do the shaded version too, but until then, enjoy the colored pups in their predicament. X3
