Frog Run

Aye, friends, it is time for another wonderful riddle. Hopefully you will enjoy it.

The frog was obviously in a hurry. It passed by the butterfly without even turning her head to salute.

“Where to?” asks the butterfly confused.

No answer from the frog, which was running like her life depended on it. The butterfly starts flying by the frog.

“Where to?” asks the butterfly again.

But the frog doesn’t waste any of her energy on talking. The butterfly thinks “what’s she running from?”

He decides to stop and wait to see what’s following the frog. And guess what? There comes another frog, just as hasty as the first. And another. They go around the lake as if some python was after them, only there’s no python. Just a bunch of other frogs watching the runners and jumping like crazy.

What is going on?
