I was playing around with the plant below. Little did I know that it is called "sea poison" Luckily, I suffered no ill effects, but if I had been suddenly struck by sea poison plant sickness, I could have used the "convenient" emergency phone below. Just follow the steps listed (in case it is hard to read in the photo):

Step 1: Break glass the glass to get key. (Either, quickly run outside the enclosure and search for a rock, or use your fist and get a more severe emergency).

Step 2: Open box with key.

Step 3: Turn right knob clockwise. You will hear two beeps. (What happens if you turn the left knob, or hear three beeps?)

Step 4: Press the side button and say slowly: "Emergency at Hide 2E. Emergency at Hide 2E." Release side button to listen. If no response yet, repeat step 4. This is beginning to sound like an episode of Lost.
