Boov

The  Boov are an intergalactic humanoid species that appear in Adam Rex's novel The True Meaning of Smekday and it's 2015 DreamWorks movie Home.

History
Boov evolved in seas of Boovworld. 100 000 years before invasion on Earth that happened in 2013, first primitive CaveBoovs appear on planet living in underwater holes. 8 000 years ago they became more social creatures, leaved caves, invented farming and start creating clans that were fighting with eachother. Also in this period they create religion based on believe that they sea was God. 100 years later they created basic tools and in next 200 years they were inventing more things like wheel, instrument called spiked tubaharp and tubaharp de-spiker.

5000 years ago first Boov went land. He run up beach, touched tree and becouse of that he won 5 dollars and latter died of asphyxiation. He became hero and inspired other Boovs to leaving water. In next 10 years Touch the Tree became the most popular sport in Boovish society it remained so for next 2000 years. During this period Boovs noticed that players had lower changes to died of asphyxiation.

4700 years were Boovs started studding science and creating art, building universities and industry. 3000 years ago all clans were united under rule of HighBoov, leaders of Boovish race and high priests of sea. They consecrated Touch the Tree as sacred act reserved only for them. However many people were playing this game in secret.

2000 years ago HighBoov closed most of schools and stared assignment of lifetime tasks to rest of population. 1150 years ago scientists started warning that industry were polluting waters and unless something change, oceans could be not longer able to sustain the life. One year later HighBoov claimed that scientists can't proved they warnings. They were named Forgotten and send onto land on exile.

In Earth year 1010 pollution of water causes death of most underwater species and oceans couldn't sustained life anymore. One year later HighBoov declared that living on land was Grand Destiny of Boovish race and entire specie leave water. During that some part of population died. In year 1011 Forgotten find Boovs, showed them how survived on land and civilization that they build on exile. 2/10 of year later Boovs banished they again and took they cities.

Anatomy
Boov are relatively short creatures compared to humans, adults are roughly the size of human children. They are amphibious and are exceptional swimmers. The Boov's have two eyes and arms with four fingers. They only appear to only have nine molars spread in their mouths that can crush material like plastic. The Boov can breath air, but through tentacle like nostrils attached to the sides of their heads like horns that they can coil. Their digestive tract is more durable than a humans, able to break down plastic, glass, motor oil, etc. The Boov have six stubby pods that they walk or run on. They can jump but not as far or high without an outside force acting on them. They don't have hair but they have feelers that look close to it. The Boov are very durable, being able to be crushed by large, heavy objects. The Boov has the ability to change color, both voluntary and involuntary. They usually change depending on their emotions or actions. Yellow is when they are scared. Purple is when their body is struck or is vibrated. Blue is when they are sad, confused or depressed. Red is when they are angered. Periwinkle is when they feel extreme fear or shock. Pink is when they feel love or affection. Orange is when they feel happiness and excitement. And Green when they lie. The Boov can control some color changes, mostly by inflicting pain.

Gender/Sexual Dimorphism
The Boov, unlike most other species, have a total of seven separate sexes: boy (male analogue), girl (female analogue), boygirl, girlboy, boyboy, boyboygirl and boyboyboyboy. Despite this, however, Boov still use conventional male/female gender pronouns depending on the feminity or masculinity of a specific sex.

Behaviour
The Boov are known throughout the universe for being the best at running away. They frequently flee from their enemies or danger. Since their previous planet spread the Boov far apart from each other, they didn't have neighbors. Because of this they don't require companionship or show affection for others. The Boov are always isolated and are often absorbed in their current activities. They don't fully understand other cultures, mistaking inedible objects for food and speaking broken English, though they appear to be fluent in other languages.

Technology
The Boov's technology is based around bubbles and plasma energy. They use bubbles as a way of storage and to help make clear domes. The plasma is used to power the bubbles and fuels their many ships. Their "Phones" are also made by bubbles and plasma using the bubbles to make a sort of screen and the plasma to power it. Their weapons consist of bubbles that can erode any substance immediately and at the beginning of the movie you see the red bubbles making holes in buildings. They have a powerful way of turning things like drinks, Slushies and more into power sources but their primary power is from bubbles and plasma.
