[Episode] "Where's Perry?" [Patches] Grub Eating Patch, Water-Finding Patch, Identifying Fauna and Flora Patch [Notes] 
Isabella found a bunch of grubs and, seeing how gross they were, wondered how she would get this patch. Later, she found out there were grubs in the s'mores she ate and that she was able to get it now. It is not shown whether Isabella gets the Water-Finding Patch or Identifying Fauna and Flora Patch, but since she made remarks saying that they would be easy to earn, it is assumed that she did achieve them.
