Observations

• Our spider let the crickets crawl over him for a
  long time then all of a sudden it grabbed one
• We put 5 crickets in to start out with but by the
  next day there was only one.
• The pepper plant is growing well but the cabbage
  plant is starting to turn yellow.
• The pepper plant has some holes in it. We think
  the crickets are eating it.
• The roly polys stay mainly under the rock
