Flight of Fancy

The internet defines "flight of fancy" as a whimsical, imaginative, or impractical idea, thought, or plan. It's something that is often considered unrealistic or unlikely to come to fruition. Think of it as a daydream or a creative idea that's not firmly grounded in reality. 

...which perfectly describes Fubar's daydream. 

Fubar, being the Walter Mitty of our little group of gremlins, has a vivid and active imagination that rarely surfaces in his daily life.  He often comes across as somewhat slow and dim-witted.  But that just might be because in his mind's eye he is performing daring and dangerous actions that demand his undivided attention.
