"Twenty Thousand Inches Under the Sea" Mr. Toad steals some artifacts from his chums and proceeds to construct a make-shift submarine. Once under the sea, Mr. Toad remembers that he forgot to include a device to return the submarine to surface.

"The Robot Dragon" The wicked Vikings use a robotic dragon to steal the kingdom's toy factory and thus frame poor Tobias. The dragon then sets out to find the real culprits and thus recover the love of the Willowmarch children.  

"The Haunted Castle" Tobias the Dragon is asked by a king to scare some ghosts out of a castle where the king wants to stay in. The Dragon is initially terrified of the ghosts, but then he realized that he knew who the ghosts were when they were still alive, and then the ghosts left the castle for some reason.

"Sir Tobias" Tobias is banished from Willowmarch when his outbursts of fire are no longer tolerated by the King. He packs off to London in search of fortune and winds up helping the Queen of England. Unwittingly, he routs her foes, and he is knighted in Willowmarch.

"Merlin the Magician, Jr." Fearing that Tobias the Dragon's daisy allergy will accidentally be sparked during a visit from neighboring royalty and perhaps precipitate "a world war," the king of Willowmarch summons Merlin's son from Ye Old Vaudeville Theater for aid. The king asks junior to suspend the daisy-curse that Merlin long ago placed on Tobias. 

"Happy Birthday, Dear Tobias" On his 400th birthday, good old Tobias must prevent his fire breath from igniting before midnight which will end the curse on him. Sir Malcolm helps him by preventing the little girl from appearing to bring her daisies.

"Dippy" The Vikings try to kidnap Tobias. To do so, the two Nordics bring a dragon egg that they present to little Daisy. The egg hatches and a small dragon named Dippy appears, but Daisy tells him she only cares about giant dragons. Meanwhile, the Vikings try to flee in their balloon dragging Tobias along.

"Gentlemen's Gentleman" Mr. Toad loses his house after the weasels seize a mortgage that he had to pay. To get the house back, Mr. Toad offers himself to work as a butler for the vermin. The weasels ignore what awaits them when toad begins to hatch a plan.

"Cowardly Herman" The King is frightened to face his own people and Sir Malcolm suggests him to fight Tobias to prove his majesty's courage. Obviously, it all will be a farce.

"Casey Toad" Mr. Toad is dedicated to his latest hobby, building model trains. The problem is that the scale he has chosen is a real scale. His friends suffer the witticisms of the conductor Toad.

The Vikings separate Willowmarch off England and tow it to their frozen land. The king commands Tobias to use his fire breath to thaw the kingdom but the dragon refuses.
