Flies

If flies are called flies
Then cats should be 'prowls'?
Monkeys 'swings'
With 'swoops' the name for owls

Bulls may be 'charges'
Horses 'gallops' or 'trots'
Ducks would be 'waddles'
Rabbits and frogs - both 'hops'

Let's refer to fish as 'swims'
Tigers as 'stalks'
Hamsters as 'scampers'
And dogs as 'walks'
Elephants as 'stomps' 
Peacocks as 'strutters'
Worms as 'wiggles'
Butterflies as 'flutters'

Bats might be 'flits'
Spiders could be 'crawls'
But sloths would still be sloths
As...

Never... 
Move...
