Dark Whelpling

Dark Whelpling summons and dismisses Dark Whelping, a dragon whelpling companion that follows you around, meaning it is a non-combat pet and will not aid you in battle.

Source

Dark Whelpling drops from Scalding Whelps in the Badlands and from Searing Whelps in the Dustwallow Marsh. The Badlands is the place of choice as the Dustwallow Marsh whelps are mixed in with a lot of other mobs that don't drop the pet. On the flip side, you will probably be dealing with more competition at the Badlands on more populated servers.

Notes

Probability of at least one drop in X kills
Number of Kills	100	288	401	693	1386	2302	2995	4603	9206
Cumulative Probability	9.5%	25%	33%	50%	75%	90%	95%	99%	99.99%
Neither the drop rate nor cumulative probability increases based on the number of monsters you have already killed.

The drop rate of this pet is 0.1% (one in every thousand kills)^[1] and takes an incredible amount of patience and determination in order to get one. Due to the difficulty of obtaining one, and thus their rarity, they can sell for fairly large amounts of gold on the Auction House, at least as far as pets are concerned.

The cumulative odds of getting at least one (1−99.9%^N) are shown to the right.

Orb of the Blackwhelp

Darkwhelp — A player in Blackwhelp Form.

In-game, players who finish part of a chain quest ( [Meeting Note]) can purchase a single [Orb of the Blackwhelp] until used up of its 4 charges. These orbs allow the player to transform himself into a larger black whelp. When a player uses [Noggenfogger Elixir] in this form, they can do a "mini-me" with their pet Dark Whelpling. Though this form is broken through combat or even falling, players like to use this item to "mess around".
