Nepeta Leijon from Homestuck's love interest is one of the trolls.
their planet is called Alternia
The Trolls are introduced in Act 5 Act 1 of Homestuck. They are a key group of characters in the story and play a significant role in the overall plot.
Karkat, Sollux, Kanaya, Gamzee, and Terezi.
In act five they show up but DO NOT SKIP AHEAD or you will not be able to understand anything
There currently are no specific birthdate for any of the trolls. But there is a character that was born in April and that is the John Egbert.
It's like a blowjob on your head. The trolls' horns are thought to be very sensitive and a spot for stimulation.
They are called trolls and skipping ahead is not recommended. However, they show up at the beginning of Act 5 Act 2.
The answer my friends is to look deep inside yourself, then if you are truly dragon born the shout will come naturally. FUS RO DAH.
They never turn into vampires. Fairly sure the Trolls show up in Act 3.
The life cycle. Well the trolls have to feel a bucket. A bucket in which the trolls have to be at least 12 sweeps to feel one. And when they do they have to take that bucket and give it to the Mother Grub. Which is this big ol' monster beast that looks like it could be a lucus. :)
The commands John was gave in first battle-thing in Homestuck E.g. Abscond was the follow the kids across the incipisphere and the trolls to the exobiology lab. Then they would all work together to come up with a plan to get rid of Jack Noir.
