The Goofy Dogs are intelligent artificially created half-human, half-dog hybrids living in 2123.
These creatures, as well as many others, have been living on Planet Earth for 100 years, but have been kept in secret laboratories since their creation in 2023.
After World War III, Planet Earth is nearly destroyed and humans colonize Mars, the Moon, and another Earth-like planet. The Goofy Dogs and some of the other creatures have run away from The Goofy Laboratories and hid to save themselves just before the outbreak of the War.
Now they live in their own city, which they manage.
Be careful, because not every Goofy Dog is as cute as it seems.
