The series first began as a preview of two sheep in Hat Films' self-produced Minecraft 1.1 Update. A spin-off video was released on the same day, this time with more characters. As the series progresses, more characters are introduced with short storylines. A spin-off series, Filfy Mod Spotlights, showcased Minecraft mods every episode.
Filfy Animals features various mobs found in vanilla Minecraft, each having their own character. The mobs are listed according to their appearance:
- Phil and Steve are a pair of sheep. Originally introduced with a coat of white wool, Phil's wool is now coloured yellow while Steve's wool is coloured blue. The two made their first appearance in Minecraft 1.1 Update to introduce several new mechanics to version 1.1. Their antics in later episodes now consist of eating everything and commenting on the taste before throwing up everything they ate. Phil and Steve also co-hosts Filfy Mod Spotlights together with Philososquid. Phil is voiced by Alex and Steve is voiced by Chris.
- Enderstalker is an enderman that stalks Ross from a distance. He occasionally falls into the water and had to spend the next few moments glitching around, desperately trying to escape the water. Enderstalker is voiced by Ross.
- Philososquid is a squid that ponders and tends to ask many questions. He can either be found on his own in a tank or with another squid. He often farts. Philososquid also co-hosts Filfy Mod Spotlights together with Phil and Steve. Philososquid is voiced by Ross.
- Tom and Eric are a pig and zombie pigman duo. They have a friendship storyline. Eric was once a pig but was turned into a zombie pigman after being struck by a lightning during a thunderstorm. At first Eric calls himself a monster, but he is now comfortable with his new image. Tom is voiced by Chris and Eric is voiced by Ross.
- Gloomy is a ghast. Due to his high-pitched voice, the other ghasts drove him out of the nether. He now floats aimlessly in the overworld. He constantly tries to communicate with the other ghasts via the nether portal, albeit with limited success. Gloomy is voiced by Alex and the other ghasts are voiced by Chris and Ross.
- Geoff is a glitchy silverfish and arguably the most well known of Filfy Animals. He glitches upwards in a similar fashion to mobs trapped in a small room in multiplayer. Wherever Geoff travels, anything around him goes up in flames. This sometimes lead to unfortunate situations, yet with humourous dialogues. Geoff is voiced by Alex.
- Foxxy is the female wolf contestant in A Filfy' Kind of Love!, a gameshow where she finds a perfect prey... on love. Ross provides the voiceover as the show presenter. At the end of the video, Geoff sets the whole place on fire. Foxxy is voiced by Kite Tales.
- Detective Claws is an ocelot detective. He has spent many years on the force and was about to retire when he was given the case on several unsolved arson. He was caught on fire while attempting to catch the arsonist Geoff. Claws is voiced by Chris.
- The Fowl Flock is a group of chickens wearing war paint. They hatched a scheme to injure Gloomy using TNT cannon but it backfired upon execution. The flock leader is portrayed by Alex while the other chickens are acted out by then Hat Films' staff moderators Thimian and Kootiepatra.
- Simon and Lewis are two creepers and have skins similar to their own Minecraft avatars. Simon loves everything, leading to some unfortunate mishaps. They are voiced by themselves.
- Matilda is Eric's zombie girlfriend. Being a zombie, she sometime gives off a cloud of zombie virus, chocking Eric. In Festive Filf, Eric tries to give her to Tom in an attempt to make up for the times he has neglected him. However, she ran off and caught herself on fire. Later in 800k, Eric found out that she is in love with Philososquid. She is not voiced by anyone as she cannot talk.
