Lana and her pet frog Hops are at Tall Timbers Park, visiting a pair of fish she calls the Fishmans, who live in the pond and have laid at least a hundred eggs. Suddenly, a bulldozer arrives, and Lana learns from the driver that the park is going to be torn down to put up a mustard warehouse. Knowing this could be dangerous for the Fishmans, Lana and Hops secretly dismantle the bulldozer to delay their progress.
At home, Lana explains the dilemma to her parents. Rita and Lynn Sr. tell her that what she should do to save the Fishmans' pond is circulate a petition and collect 10,000 signatures. However, Lana finds that task too daunting, and after she accidentally scares Leni (who mistook her for a monster because she was covered in mud), she gets an idea. With the help of the animals in Tall Timbers Park, Lana disguises herself as a swamp monster and successfully scares off the construction worker. The construction worker tells about the monster sighting to the news, and the mustard warehouse is announced to be relocated.
The next day, however, when Lana returns to the lake, she finds dozens of people waiting to see the swamp monster make a reappearance. To get the people away from the lake and leave the Fishmans in peace, Lana uses her monster disguise to scare some people over at Short Shrub Creek, which sure enough gets the attention of all the people who were at Tall Timbers Park and gets them to leave. Unfortunately, when watching the news later that day, Lana then finds that Short Shrub Creek was the exact place where the mustard warehouse construction had moved, and they've now moved construction back to Tall Timbers Park, thus putting Lana right back where she started.
Hoping she still might have a chance to save the Fishmans, Lana goes back to her parents' original suggestion and goes all over Royal Woods, asking the neighbors to sign her petition. Unfortunately, she comes up "about ten million short," and comes home admitting defeat. But just then, Lisa notices a photo Lana took of the Fishmans and recognizes them as being lake sturgeons, which are an endangered species. To Lana's delight, this means that the lake, and therefore the Fishmans, are protected by law.
Notes[]
The gag with Lana hearing her parents' (and later Lisa's) ramblings as trombone sounds is a reference to the Peanuts animated specials, in which the adults' dialogue were represented the same way.
