The Case of the Lost Critter

**The Case of the Lost Critter** is the second episode of the first season of Fishtronaut.

## Summary

The episode opens with Fishtronaut decorating for the annual S.E.A. (**S**ecret **E**nvironmental **A**gency) Costume Party asking his partner Agent Rosy Barb to know what she will dress up for the costume party. Rosy asks him that Fishtronaut must have decided for what costume he will wear for the party. He thought of wearing a fishbowl costume, which would be better than the costume worn last year. Rosy agrees with Fishtronaut's thought about the fishbowl costume for the party. Fishtronaut receives a P.O.P. when talking with Rosy and then takes it to Marina while he tells Rosy to meet her in the costume party soon. Fishtronaut then brings the P.O.P. on the spot where Marina is at as Fishtronaut and Marina tell the viewers to dance to the rhythm to open the P.O.P. sent by the S.E.A..

**P.O.P. Clues:** a pacifier and a compass

Receiving the clues, one of the clues Fishtronaut received is a pacifier, an object to help babies calm down. Fishtronaut then thinks the pacifier clue has something to do with a baby and the other clue received is a compass (an object used by people to find out where they are) and the compass clue means there is a lost baby somewhere in the park that must be reunited with its parents. Having solved the clues, the mission is to find out what animal in Smiling Trees Park lost a baby. Zeek then arrives to the two who are on a mission to find a lost baby in the park as the trio decides to go to any spot where a lost baby could be. The trio arrives to Monkey Island on a family of marmosets (a type of monkey, just like Zeek) as Fishtronaut asks the father marmoset to know if he lost a baby. The father marmoset then checks to know if all of his babies are here on their home Monkey Island. Zeek is then curious marmosets and Marina explains that baby marmosets are one of the smallest monkeys in the world. The father marmoset then arrives and tells them that everything is fine with his family, including his babies.

After leaving Monkey Island, Marina is curious that the baby lives underwater instead of living on land. Fishtronaut then asks Rosy Barb that there is an unknown lost baby in the park. Suddenly, Billy and Mac have a baby creature by forcing it to have some of their snacks, such as soda and French fries, while their conversations bother Marina on the search for the lost baby. Billy and Mac are forcing the small creature to have some of their snacks, but it won't eat their snacks. The gang meets them what the twins were doing and were trying to feed the small creature (thought to be their pet). The small creature from the river doesn't feel happy, refuses to eat some of Billy and Mac's snacks, and wants to go back to its home with its mother and the creature comes from the rivers. The twins decide to return the small creature to the trio. Having retrieved the creature, the trio decides to return it to its mother. However, the trio is curious to find what critter the three found.

Fishtronaut uses his invention the Critterdex to help identify different types of animals. While putting the critter on the Critterdex, the Critterdex says, "Platypus" after identifying the baby platypus on the Critterdex. The gang is curious that they have never heard of the word "platypus" and the platypus is a furry animal with the beak of a duck (Fishtronaut also says that ducks have feathers, not fur like the platypus). The trio decides to visit the ducks to know more about the platypus. Suddenly, Rosy Barb hears an adult platypus crying on the lake while decorating for the costume party. Rosy asks the adult platypus that if she is lost. The platypus says that she is not lost, but she lost her baby. The mother platypus then explains that while she was looking for food during the morning, her baby disappeared after returning the spot where her baby is supposed to be; therefore, the mother platypus won't calm down until she has her baby back. She asks the mother platypus to tell her friend Fishtronaut to help her solve the case.

Meanwhile, the trio meets a mother duck while Marina shows the baby platypus to her to say if she lost any eggs and the platypus is one of her babies. The duck, however, says she didn't lose her eggs and the platypus isn't one of her babies. While trying to find his mother, Rosy asks Fishtronaut saying that she found the mother platypus looking for her baby. The baby platypus feels excited that he wants to return to her mother. Fishtronaut decides to return the baby platypus back to his mother. Before Fishtronaut returns the platypus to his mother, Marina is very curious to know what kind of animal a platypus is. Suddenly, another P.O.P. arrives towards the trio.

**P.O.P. Rewards:** the Big Book of Mammals

Receiving the reward, it is then known that the platypus is a semi-aquatic mammal (which lives on land and on water) that lives in Australia and the platypus is a strange animal that lays eggs, according to the Big Book of Mammals. Marina found out that she has to show the Big Book of Mammals to her cousins Billy and Mac while Fishtronaut decides to bring the baby platypus to his mother in the lake. After reuniting the baby platypus to his mother, Fishtronaut tells her to be in the costume party. Suddenly, many S.E.A. agents arrive to the costume party. Fishtronaut is dressed as a platypus, which is a fantastic costume better than a fishbowl. Fishtronaut is also excited about Rosy in a Bubblex suit similar to Fishtronaut's is a great costume. Suddenly, Happy Plumb arrives wearing a Bubblex suit who likes Fishtronaut's platypus costume.
