and the waxy squirrels , which are all little punks , teasing you if they see you , teasing themselves if they do n't , and the rusty squirrels , which are like dumb little kids , and sometimes there 's swamp foxes out in the leaves who you can hear faking their noise to sound like the squirrels they eat and even less often there are mavens singing their weird maven songs and once i swear i saw a cassor running away on two long legs but ben says i did n't , says the cassors are long gone from the swamp .
