The first illustration is perfect for the song 'Shotgun' where they sing 'Homegrown alligator, see you later' :D It made me think of it instantly :) These little aliens seem to be concerned about so many aligators around them :)

The house worm doesn't seem to be a pleasant visitor at your home but this roof licker could be a good thing when you need to clean your windows :D

Thank you for sharing these two funny illustrations! :)
