-I live, and I live at Mistmantle! I'm an otter! Fish, friends, water! I'm an otter! Isn't wonderful? - Fingal
Fingal greatly looks up to his older brother, Padra. He copies his brother when the Hedgehog Host tries to assassinate King Crispin. Though they are similar, Fingal is younger and rather childish. He is very friendly and outgoing, as he reachs out to many animals, such as Scatter. Even though he is immature and freespirited, he can also be responsible when times get serious. When Crispin asks if Fingal would like to join the Circle, Padra says to not do it because he would have wanted to play a little more.
Fingal is born to an unknown otter male and female along with his older brother Padra. Close before the prologue in book 1 there have been a rage tide where Fingal lost his parents in. Padra promise to take care of his little brother, and send him to a place far away from the tower to be safe. It is a place where only otters live and "everyone takes care of each other". This is why he developed a friendship with Mother Huggen.
Fingal first appears to with Padra in the battle to overthrow Husk. There had been rumors heard around the tower of Padra having a little brother and that he was sent to live with a colony of otters when the culling law was made. Fingal is also mentioned by Mother Huggen which says that it's safest for Fingal to be away. If Padra had been arrested, Husk would probably have tried to find everyone on his side and then be especially after his family and at the time, Fingal was his only family member.
Fingal, Hope, Needle, and Sepia all go looking Sepia's song cave for the missing Heartstone. Fingal found the waterslide that led to the underground lake, and the future "ottery", by following Hope. Fingal did manage to find Hope and met Needle and Sepia back in the throne room after the two had quite an adventure in the tunnels.
Fingal is first seen eating with his family on the beach before a night of Riding Stars and jabbering happily about his new boat that Twigg was building for him. During Catkin's naming ceremony, he is seen sitting in the crowd along with Tide and Swanfeather.
He, Crackle, and Scatter find the source of the Fouldrought, which was a dead, rotting fish blocking up a stream. He sends Crackle back to the Tower to report their findings but has a harder time sending Scatter with her until he yells at her to go. He then builds a fire and burns the fish. The winds turn and Fingal is burned, however, against his orders, Scatter had doubled back and returned to him and saves him.
Fingal is honored along with Crackle and Scatter for ending the sickness and is given a silver bracelet.
The storm that causes the huge landslide wrecks his boat by crashing it against the rocks so only a few pieces remain. Fingal is heartbroken but doesn't say too much about it. Families who felt they owed a favor to Fingal secretly rebuilt his boat.
Fingal carries Sepia out to sea on his back to Linty's boat helps Sepia rescue Catkin. Fingal finds some pride in the fact that his boat had been destroyed, as it was a piece of wreckage that saved Catkin, Sepia, and Linty.
Fingal is first seen racing his nephew, Tide, on the shore while his niece, Swanfeather, while Princess Catkin watches. When Catkin proclaims Tide the winner, Fingal teases her about proclaiming a lot of things. He is the first one of the four to notice the approaching swans, and tries to be of service, but is cut off by Catkin who leads the party of swans to the Tower.
Fingal and Padra were the ones to rescue Corr when he got caught in the riptide, while he was coming to warn the king of the ship-fulls of ravens coming. Fingal showed Corr the ottery, which later helped Urchin and Juniper escape from the besieged Tower. The two later swim out to untie and escape with Catkin along with Padra's twins.Fingal also helped with the fishing nets that trapped the ravens along with his new sidekick, Corr.
It is revealed that Fingal and Padra's father was killed during a rage tide and Padra has since taken care of and raised Fingal.
When the senior members of The Circle are discussing the prospect of some new Captains with some new blood, Fingal gets suggested, however Padra says that they should let him have fun for a bit longer.
Fingal helps with the evacuation of the tower and is part of the 'Circle of White' that is formed to aid the animals during the flood.
After Crispin's death, he remembers him with laughter and happyness instead of greif.
