Agent Binky: Pets of the Universe - Season 1

When Small Human hears a bump in the night, Binky and Gordon head to the Room of Many Boxes (aka attic) to check things out. Not only do they find aliens (code name: mosquitoes), but there is also a giant alien there too, or so they think. It turns out to be a bat named Amelia, who is an undercover PURST agent who wants to get rid of the aliens herself. Only when they team up as PURST members should, do they succeed in removing the aliens.
