The Complicated Sentence Game!
 

This game is quite simply, you take the sentence before hand and you make it longer by taking nouns, pronouns, verbs, etc. And replacing them with something a little more complicated. For example lets take the sentence

A man walked into his house.

You then complicate it in the next post by

A human stode into his living room.

And then the next sentence

A bipedal mammal used both his legs in a one after another motion to move into a building which was considered shelter for him.

And the so on and so forth. And now I shall start you off with this sentence.

A dog and a cat watched each other from across the street.

A canine and a feline set eyes upon the other mammal from opposite sides of the thoroughfare.

one mastiff and one kitten were glancing over at eachother from opposite sides of the roadway.

A scruffy canine and a furry feline glanced nervously at each other across the busy, bustling roadway.

The mangled appearing St. Bernard and the luxuriantly furred minx glared ominously to one another, the gaze only interrupted by the flying automobiles on the asphalt lain trail.

A rather seedy appearing mammal descended from the canidae family as well as an unkempt domesticated feline stared rather intently at each other beyond a path that multiple automobiles traversed often.

A somewhat disreputable or squalid-appearing mammal that was a representative of the taxonomic family distinguished by its members being digitigrades and for the male's bulbus glandis physically locking the male and female together during copulation as well as a common domestic variety of the feline family stared rather intently at each otherr beyond an area of earth cleared and paved for the purposes of easy travel which was frequently traversed by four-wheeeled vehicles powered by internal combustion engines.

...this isnt going anywhere after that sentence so I think I'll get a new sentence going.

The man was going across a large field when suddenly a meteor struck the mountains.

The human male was striding to the other side of an enormous clearing filled with grass when suddenly a large rock from space collided with the large rock structures sticking out of the ground.

The homo sapiens possessed of an equal count of X and Y chromosomes was ambulating across a span of dirtbound organic life when an extraterrestrial stony-iron boulder containing large amounts of both metallic and rocky material made direct contact with the massive forms of stone and dirt which emerged from the earth in times of old at inestimably high speed, unexpected by the aforementioned biped.
