Fishtronaut
The Case of the Rain Maker
S2 E37:
An inventor Jerboa tries to create a rain-making machine, earning the admiration of Fishtronaut and jealousy of Zeek. To prove himself more inventive than this visitor, Zeek tries to fix the river rats' dried up pond on is own, but ends up causing a flood instead. The Jerboa actually uses Zeek's project to help resolve the problem, combining it with an invention that already existed.
