Riddle Explained: The Mellow Giant That Picks Up Logs and Sprays Water

The riddle says:

"This mellow giant picks up logs for fun
And sprays water from its long trunk."

Let's break it down step by step:

1. Mellow giant: This suggests something large and gentle.
2. Picks up logs for fun: The subject interacts with logs — perhaps lifting or moving them effortlessly.
3. Sprays water from its long trunk: The word "trunk" is a key hint. In nature, an elephant has a trunk used to spray water.

Putting it all together, the "mellow giant" with a "long trunk" who "picks up logs" and "sprays water" is an elephant. Elephants are large, gentle mammals known for using their trunks to pick up objects (including logs or branches) and to spray water for drinking or cooling off.
