The Well Dweller is an episode from the third season of Garfield and Friends.
While drilling for water, Orson encounters a strange little creature named Al. Orson's brothers try to steal what little water the farm has left and Al.
It's a hot day and Orson's Brothers are roasting out in the sun. Mort tries to use the pump, but they have no water. So, being the rotten pigs that they are, they decide to head over to Orson's farm and take his water.
Meanwhile, on the farm, Orson needs Bo's help to dig for any water. However, after they dig a hole and Orson drops a pebble in, there's no splash, indicating a severe shortage of water. As Orson and Bo leave, a strange creature pops out of the hole and starts to walk on the farmland. Wade walks by and notices the creature, frantically stammering at such a sight.
The farm is down to just a tub of water and Orson locks it up so it can be reserved for emergencies. As they leave the barn to continue digging, the creature happens to sneak in and attempt to get the water, but he sets off the alarm. Orson catches it and it reveals its name to be Al. He lives in an underground city. He was casually strolling and got hit by the pebble Orson dropped and wanted to tell him not to do it. He also wanted to get a drink of water due to the heat, and Orson gives him a glass of it to hydrate him. Orson's brothers notice Al and wonder what they can do with him.
They attack Orson, Bo, and Al. Al does not take kindly to their hostility and attacks them with a magical beam he has the power to shoot. This causes Orson's brothers to run away while the others until Bo and Orson. They take Al back to the hole Orson drilled and worry about the lack of water they've been suffering from. Al offers to get them some water, but Orson doesn't believe it'll happen since he's dug there as far as it can go. Just then, the well bursts with a geyser of water coming out, courtesy of Al. Orson thanks Al, hoping he heard it. Wade realizes that the water is coming down on him and he runs in fear while the others rejoice in their newly obtained water.
