Jumping off of pumpkin/melon sprouts makes the same sound as walking on planks

If you jump off of a pumpkin sprout or melon sprout, the sound it makes as you jump is the same sound that it makes if you are walking on wood planks.

How to reproduce:
1. Plant some melon/pumpkin seeds on farmland.
2. Walk on the sprouts and jump.
3. Listen for the sound of walking on planks.
