D&D 5E Monster as PC for one shot adventure suggestions!

[HawaiiSteveO]

Party is 10th level, instead of playing PC thought it would be fun to play a critter instead.

Not that it matters, party has rogue, cleric, and fighter type.

Bone/Spirit Naga, Red Slaad, Mummy, Werewolf, Hill Giant, Dragon Wrymling (pretty much any), Chain Devil can all be fine PCs. Start with it as a PC, treat as 10th level, and then to advance (should the game continue) have them 'multiclass' into normal classes. Alternatively, use Volo's guide to make a more humanoid monster into a PC (bugbear, etc...) and just add 10 level of classes to it.

Have you read through the Monstrous Adventurers section of Volo's Guide?

I always thought about an awakened ooze with modified spells that deal acid damage. It can have intelligence, but low wisdom since it was recently awakened. It can be awed by many things and store items inside of it. Kind of slow with poor Ac though.
