Mouse (Books)

Mice are mentioned minimally in the How to Train Your Dragon Book series.

Description
Mice are very small mammals commonly known for their relatively large ears, squeaking noises, and their nuisance potential. Mice species comprise the Genus Mus and occur world wide, in part to their high level of adaptability. Despite their relatively short lifespan and low position in the food chain, mice are a highly successful group of mammals with a high breeding rate.

Mice generally are herbivorous, eating seeds and plant material, but this is also dependent on habitat and are able to eat a wide range of foods if necessary.

Vikings may have encountered the House Mouse (Mus musculus) as well as other closely related mouse-like species such as the Wood mouse (Apodemus sylvaticus) and the Eurasian harvest mouse (Micromys minutus)''

Function
The Book series indicates that mice are prey for smaller sized dragons. In reality, mice are prey for a large variety of predators, even humans and some invertebrates.

Mice are also kept and bred as pets. They are also a model organism for scientific research.

How to Train Your Dragon
Stoick the Vast has a mouse problem in his bedroom. When Toothless wakes up from his Winter hibernation hungry, Hiccup and Fishlegs put him in Stoick's room to eat the mice.

"They put Toothless in Stoick's bedroom, where there was a mouse problem. For a while he was happy swooping after the desperately squeaking mice, but then he got bored and started attacking the mattress."
