I thought of turtle....what's the Opp -wait, turtle starts with T T rhymes with E E is fifth letter of the alphabet, alphabet may be short for alpha beta but it's missing only one letter, 5-1=4,4 is the only number that when spelled has the same amount of letters as the number they represent, another only in the world is the bat, only mammal that can naturally fly, flies are a nuisance, odor is also a nuisance, febreeze takes care of odors, febreeze comes in a bottle, so does water, waters enemy is fire, fire can be found in-the opposite of turtle is volcano!
