This unnamed female troll is a character that first appears in the episode "Chapter 4: The Sparrow Scouts", and has a supporting role in "Chapter 5: The Troll Rock". The character also appears in the Hilda Tie-In Series, but not in the graphic novels.
Physcially, the troll doesn't look any different than the other trolls seen in the animated series. Her body looks like a large boulder, with stumpy arms and legs, white blank eyes, and a long nose.
In "Chapter 5: The Troll Rock", the troll discovers her child has gone missing, and realizes it is in the city. Since she can't break through the wall, she uses the Vittra tunnel to get into Trolberg. It takes her two nights to make the tunnel big enough for her to fit through.
Near the end of the episode, she tracks down her child to The Ahlberg School, and startles Ms. Hallgrim. Hilda is able to convince Ms. Hallgrim not to raise the alarm, since she realizes the troll just wants her baby (who, at this point, has been causing a lot of chaos in the school), back. Hilda is able to capture the baby and return it to the mother. As expected, the two trolls immediately leave, but the mother stops for a moment to smash the new statue of Edmund Ahlberg. The two are not seen again afterwards, and presumably managed to get out of Trolberg unseen.
The plot of "Chapter 5" is also adapted into "Hilda and the Great Parade", where it gets combined with "Chapter 3: The Bird Parade" and "Chapter 7: The Lost Clan". In the book, the Troll's child also ends up in Trolberg, forcing the mother to follow it. The book doesn't reveal how the troll got into Trolberg, though David remarked earlier that the wall near the village of the Bragga Family is rather fragile and crumbling, and a troll could probably smash through it if she wanted. Another difference with the animated series is that, instead of a statue, the troll wrecks the Ahlberg School's float for the Bird Parade (which depicted Edmund Ahlberg standing on a dead troll).
