Durandoo

"Simple walking creature encased in a hard shell. Often found wading in shallow pools of acidic water. One of the few creatures that can survive in the rivers of harsh acidic water that flow around us. Where does this water come from? It bubbles and spits with a seething hatred of the living..."

Durandoos are enemies in Hollow Knight. They are large, armour-shelled bugs who frequent shallow pools of acidic water. A similar winged creature called Durandas can be found in the same areas.

Behaviour and Tactics
Slowly swims back and forth passively in acid pools. It can be used to traverse above acid before acquiring Isma's Tear or Crystal Heart by downstriking it as it cannot be harmed this way due to its spiky shell. Similarly to Durandas, it only takes damage from the front; however, it is rather difficult to hit it with the Nail without Isma's Tear, so the use of Spells is recommended.

Location
They can be found in the Queen's Gardens and in Greenpath, to the west of Stone Sanctuary.

Trivia

 * The location where the Durandoo can be Dream Nailed is in the southeast section of Queen's Gardens that has an acid lake with a Durandoo in it. The ground aside the lake is at face-level with the Durandoo allowing the Dream Nail to reach it.
 * Its shell has a separate hp value of 9999, though it cannot be damaged.
