The whole peepeepoopoo army fricks alot

There is a character named Virgin Turtle.

Lots of fricking involving turtles as well as villagers whom Felix does sometimes watch create bebes.

There is a scene where the dog fricks a turtle, while the turtles husband watches

Pewds makes a "frick chamber" where the villagers in it are supposed to constantly make babies.

In the later episodes there is much more sex

Season 2 is full of sexual activity and sexual jokes

Felix accidentally makes Sven frick his son. The resulting baby dog is named Alabama.

Many virtual animals and monsters are killed throughout every episode. Any of the many deaths of one of Felix's pets can be a bit more intense.

Many Creepers have blown up in very close proximity to Sven.

Felix constantly gets into fights with hostile mobs. Most of the time he wins, but on rare occasions he'll die. However, he re-spawns every time.

Pewds mentions "Boobs" and "Vagana"

Pewds fights a boss based off himself that says the naughty F word as well as the S word.

Pewds constantly insults and threatens Water Sheep.

Although Felix censors most swears, some slip through (Such as bitch or fuck)

Most language is censored but there is lots of damnits and what the hells and sometimes he says ass, bitch, shit and on very strong occasions fuck

Consumption of various potions occasionally occurs

Not really anything maybe some references

A lot of the main characters die.

This series shows material that could be particularly traumatizing for children who are not 9 years old, Vegetarians, and members of PETA
