King Cobra in Pet Simulator 99

Public sources checked 2026-11-02

King Cobra is a Basic pet from the Sandcastle Egg in Spawn World. The egg’s public data lists King Cobra with weight 0.125 alongside weights 100, 30 and 3 for the other pets. Those entries do not sum to 100, so 0.125 is not a verified 0.125 percent final hatch chance. The older wiki price is 150 gold bars, a single-source historical figure rather than a current shop quote. Huge King Cobra and Huge Evolved King Cobra are separate pets with their own acquisition paths and prices.

Wiki power readings are 829 normal, 1.04K golden and 1.29K rainbow. On 2 Nov 2026 PS99RAP listed normal RAP 1,234 and 5,543,593 in existence. The official RAP feed agrees on normal 1,234; its 2,374 row has pt: 2, which marks rainbow. That is a different variant rather than a conflicting normal price. Cosmic had no matching King Cobra row. PS99RAP and the official feed use the same underlying RAP, so these endpoints count as one market-data stream.

Use it as an early stat pet and a collection slot. It will not carry a late area the way a Huge does, because Huge damage is defined as always above your best stat pet. If you are buying one, match the variant in the trade window to the column you read. A golden or rainbow cobra is a different row from the 1,234 normal.
