Are there any other Gnoll/Hyena related statblocks?

Question

I am planning on building a high-level “Yeenoghian” multi-part epic encounter, using only official material, in the scope of Adventurers League play.

Are there any gnoll/hyena-related statblocks other than the following?

• Gnoll
• Gnoll Hunter
• Gnoll Flesh Gnawer
• Gnoll Pack Lord
• Gnoll Fang of Yeenoghu
• Gnoll Witherling
• Flind
• Hyena
• Giant Hyena
• Shoosuva
• Yeenoghu himself

Related here means that the potentially missing statblock(s) would have a strong link of association with gnolls, hyenas or the Demon Lord Yeenoghu, and/or would physically look similar to either of them.

Answer 1

You missed Gash the gnoll (a CR 1/2 NPC) from Out of the Abyss among the creature blocks with the gnoll tag (D&D Beyond Search).

For creatures with a strong link to gnolls, the section in Volo's Guide to Monsters on gnolls includes a subsection on Gnoll Allies (p. 38). They are:

• Demons. In addition to Yeenoghu, the book suggests:

  • barlguras
  • dretches
  • hezrous
  • manes
  • maw demons

• Ghouls

• Hyenas (already covered in question)

• Leucrottas

• Trolls

• Also associated with gnolls are cultist of Yeenoguh which can be any type of humanoid using a variety of statblocks, but maybe in particular cultists.

Also, Yeenohu's own lil' pupper; Crokek'toeck from Baldur's Gate: Decent into Avernus (p. 230) deserves a mention. (Thanks Sdjz)
