This riddle describes a creature that is calm and large, called a 'mellow giant'. It says this giant 'picks up logs for fun' and 'sprays water from its long trunk'.
Let's break it down:
1. 'Mellow giant' suggests a big, gentle animal.
2. 'Picks up logs for fun' means it uses its strength and trunk to pick up big branches or logs.
3. 'Sprays water from its long trunk' tells us it has a long nose (called a trunk) it can use to squirt water.
Which animal fits all these clues? It's the elephant. Elephants are very large and peaceful animals. They have long trunks, which they use to grab things like tree branches (logs) and can spray water to drink or play.
