Theory:

     It was really the crocodile who winked at him. “Excuse me,” said Golu. “Have you ever seen a crocodile?”
 
     The crocodile winked again and lifted half his tail out of the mud. “Come here, little one,” said the crocodile. “Why do you ask such questions?”
 
     “I want to know...”
 
     “Come close, little one, for I am the crocodile,” and he shed crocodile tears to show it was quite true.
Explanation:
 
It was a crocodile, not a log that Golu had noticed on the riverbed. And Golu, unaware that it was a crocodile, inquired as to whether it (crocodile) had ever seen a crocodile. The crocodile winked once again, raising part of his tail from the mud around him.
 
The crocodile asked why Golu was so fascinated by it and asked so many questions about it. Golu told the crocodile that he wanted to know about the crocodile. Taking advantage of the baby elephant's curiosity, the crocodile decided to play a trick on him.

The crocodile's plan
 
The crocodile asked Golu to approach it and disclosed that it was the crocodile Golu had come to meet. It also shed crocodile tears to reassure Golu that what it said was real.
 
Crocodile tears, on the other hand, refers to the fake, afflicted tears. It's based on the idea that crocodiles cry to lure their prey. Crocodile tears help the crocodile get its victim because the prey will trust the crocodile's tears and approach it closer.
