Pikachu is not totally fiction after all,
There's this cute rodent called Pika,
This Pika is Pikachu's inspiration,
Found in the foothills of Sikkim,
But the scientists think it's new,
Pika is one tiny Indian rodent,
Its standing posture, its ears,
Have been the inspiration,
Not just now but for long,
Since antiquity it's there,
Only now got discovered.
