The Origin of the Coconut

You can read more about Trishanku at Wikipedia. Here is the graphic from Amar Chitra Katha:

Trishanku wanted to enter heaven with his mortal body. Assisted by Sage Vishvamitra, he ascended, only to be thrown down by the devas. As he hurtled down, Vishvamitra propped him up with a long pole. The pole changed into a coconut tree. Trishanku's head became the nut and his beard, the fibre around it. Take off the fibre and you can see his eyes!

Here is a picture from Wikimedia showing the "face" you can see in a coconut:
