|27 years under a coconut shell...|
Kermit: I spent 27 years in the same job. I feel like the frog who spent his life under a coconut shell.
Such stories may depict the frog as insular or foolish. But some cultures have seen the frog as an animal that undergoes many changes in its life: egg to tadpole to amphibian. Even to handsome prince! And it can be a symbol of fertility (because of the number of eggs it lays). Also of transition or rebirth as it passes from tadpole to frog. And cleanliness because of its diving in and out of water.
