While on a field trip to Oceanland, Angela falls in love with the whales. She wants to become a marine biologist. Grandma Lou is over for a visit and she's brought along a periscope. This piece of equipment is all Angela needs to begin. She is soon at the beach with her friends, searching for signs of sea-life. They happen upon Ms. Yamagachi's scuba diving class. What luck! Angela would love to take lessons. Unfortunately, she's too young. Nanette is in the class; however, she has previous experience bought for her by her father. Angela needs scuba experience in order to take the class. She will need an instructor. Grandma Lou will do in a pinch! Grandma Lou won't let Angela swim in the lake for her first dive, too dangerous. They need to find a pool. Nanette has a pool but she would never let Angela swim in it. Grandma Lou suggests that they use it anyway, when nobody is looking. Of course, they get caught. While in the pool, Angela finds some jewels Bunny Manoir was missing. Angela falls in love with the rocks and decides that instead of marine biologist, she'll become a geologist. (thetvdb.com)
