"Well, well, well! Two big engines afraid of a cow?"
Edward teasing Henry and Gordon, Cows

Daisy, Bulls Eyes

An inquisitive bull who was angry, had once strayed from some farm labourers and ran away. He eventually came across the railway and seeing grass on either side, began to eat. Daisy tried to shoo him away, but was scared away by Champion and backed away, until Toby came and frightened him away.

"I'd rather be as right as rain than as wrong as ice!"
— Dilly, Surprise Adventures

After Donald teased Duck about his "quacking", Duck's crew got revenge by slipping a small duckling into Donald's tender. When discovered, she became friends with Donald and his crew and eventually settled down at Haultraugh (Tidmouth Hault in the television series), where a small pond was nearby. She was named Dilly by the stationmaster, but she is known to everyone else as Donald's duck.

In an annual, she disappeared for a few months, only to return to the station with her husband and children in tow.

Animals in the television series

This section is for animals that only appeared in the television series:



Gordon had problems with his fire. The firelighter suggested it was caused by gremlins and Gordon later collected a special passenger. At Wellsworth, the passenger's Dalmatian ran away and ran into Thomas' cab after confronting a bull. At Brendam, Thomas enquired about the visitor and the Fat Controller revealed she was his mother, who then aptly renamed her dog "Gremlin". He also appeared near Callan station with two women as the Fat Controller drove by in his car.

  • Gremlin's original name is not known, as it was never said.



Mutt is Billy Twofeathers's British golden-doodle dog, who appeared in the film, Thomas and the Magic Railroad. He was played by two dogs, Bently and Dita.


Thomas & Friends





When Allicia Botti came to Island of Sodor, Thomas was chosen to take her with Annie and Clarabel. While being cleaned, a strange squeak came from the coaches. It kept up as Thomas went to Brendam and when he arrived, it was found that a small mouse had found its way into Clarabel's compartment. Because Thomas did not feel important anymore, Percy took over. The mouse was given a mouse hole in Tidmouth Sheds and was named Allicia by Thomas.


Thomas & Friends



Pegasus is a cart horse who lives on a farm near Dryaw Airfield. After he foolishly wandered into a ditch, Harold winched him to safety. However, Percy saw Pegasus being pulled through the air and thought that Pegasus was flying.

"All aboard! All change! Full steam ahead!"
— Fred


Fred is a red and green parrot who now resides at the children's zoo. Thomas had to take Fred to his new home, but the talkative parrot caused a great deal of confusion when he mimicked the guard and driver's voices and used railway phrases. However, Fred saved the day when Thomas and his driver forgot a very special job. The parrot, using the Fat Controller's voice, reminded Thomas and the driver that they had to pick up a surprise parcel for Lady Hatt from the harbour. After this, Thomas was sorry to see Fred go. Fred picked up his railway terminology from his time spent at the main station. Fred appeared in the 1998 magazine story, Potty Parrot!


"Fetch, Rick!"
— The guard ordering Rick to fetch the Fat Controller's timetable

Mister Mighty


Mister Mighty is a Shire horse that works at a farm along Thomas' branch line. Once, he was replaced by Terence for a day.

He appeared in the 2001 magazine story, Mister Mighty!

Sooty is a cat with a knack for trouble. Once, he jumped into Clarabel's guard's window to see the world. However, when Thomas took his carriages to a dairy factory, Sooty hopped off Clarabel and climbed onto the factory's rafters. He was saved by a fireman, who climbed up a high sail and lured the cat with fish. In the end, Sooty made a deal to stay at the shed and Thomas' driver would give him some milk and a fish daily. He appeared in the 2003 magazine story, Cat Got the Cream!


"Oi! That scamp made off with my lunch!"
— A workman

Scamp is a friendly and rather mischievous red squirrel that was brought to Sodor from the Mainland for the children's zoo. When he first arrived on the island, he was frightened by a loud noise and ran off. He then went on to cause trouble all over the island. He stole workmen's pies, the peanuts from Gordon's buffet car and Lady Hatt's seed cake. The Fat Controller then found the pesky squirrel asleep inside Annie. He appeared in the 1998 magazine story, The Red Squirrel!

Icy Blast


Icy Blast is a racehorse that Percy once took for a run in the countryside with his jockey and trainer. After his run, the jockey covered his horse in blankets.

"It's Tiger!"
— James

Tiger is the Tidmouth stationmaster's pet cat. Tiger once went missing and a reward of a day off was to be given to the engine who found him. The cat remained missing for over a week until James puffed out into the countryside trying to work out why he smelled so horrible. The cat, who was hiding in a nearby tree, leaped onto James' tender, drawn to the fishy smell. The cat was then returned to the stationmaster and James and his crew got the promised day off. Tiger presumably got his name because of his resemblance to a tiger. He appeared in the 2005 magazine story, Something Fishy.


"Hello, Wag! You always look very pleased to see me!"
— Thomas

Wag is a little dog who belongs to the stationmaster of a small country station on Thomas' Branch Line. He is very friendly and loves seeing Thomas.
