Water Strider

The Water Strider is a harmless critter that spawns on bodies of water on the Surface during the day. It only spawns near Sand and Jungle grass blocks, but not in the Ocean biome. It will not spawn if the wind speed exceeds 20 / 10. The Water Strider moves by gliding on water and hopping around on land. Due to having only 5 health and no defense, it is often killed instantly by enemies or players. Gold Water Striders have a chance to spawn in place of the regular variant.

Trivia

 * The Water Strider design appears less like real world water striders, and more like the Pokemon character Surskit which seems to be based off of real world water striders.
 * Because of the specific spawn conditions, the Gold Water Strider might be the rarest critter in the game.
