15 monsters and races that I'd want to include in my D&D campaign

No matter what, I'd like to work these in. Any I'm missing that are super fun?

1. Oblex: "an extraordinarily intelligent ooze created by mind flayers that fed on other creatures' memories. They were capable of using those memories to create replicas of their victims, which they used to further hunt and feed." - The Forgotten Realms Wiki
2. Kenku: "Haunted by an ancient crime that robbed them of their wings, kenku wander the world as vagabonds and burglars who live at the edge of human society." - D&D Beyond
3. Changeling: "A changeling can shift its face and form with a thought as a form of artistic and emotional expression." - D&D Beyond
4. Shifter: "humanoids with a bestial aspect." - D&D Beyond
5. Loxodon: "Humanoid elephants, loxodons are strong, calm, and wise." - D&D Beyond
6. Abyssal chicken: "Abyssal chickens were small creatures. They had leather wings but were not capable of sustained flight. Their wings were folded above them, giving them a tear-shaped appearance. They had a large mouth filled with fangs and a long tongue. Abyssal chickens' primary form of locomotion was their two large legs, which ended in feet resembling those of a regular chicken. Each foot had three large claws." - The Forgotten Realms Wiki
7. Awakened tree: "an ordinary tree given sentience and mobility by the Awaken spell or similar magic." - Roll 20
8. Dryad: "fey-maidens who acted as the protectors of forests and trees." - The Forgotten Realms Wiki
9. Flumph: "A flumph's body was shaped like a flat saucer with a diameter slightly larger than a human from shoulder to shoulder, and about as thick as a human arm. Flumphs floated by means of an innate anti-gravity field,[7] and moved by using air jets as propulsion. In fact, they were named after the characteristic sound made by these jets. Flumphs also glowed faintly in different colors depending on their mood" - The Forgotten Realms Wiki
10. Gelatinous cube: "a ten-foot cube of transparent gelatinous ooze, which is able to absorb and digest organic matter." - Wiki
11. Merfolk: "Merfolk are an amphibious race, born and at home in the water but comfortable on dry land. Humanoid in form, they have skin of ivory, silver, russet, blue, or deep purple. Long fins extend from the backs of their forearms and calves, and their fingers and toes are webbed. The hairlike growths on their heads are either thick and bristly like the needles of a sea urchin, or long and wavy, resembling fine seaweed. In either case, these growths typically range in color from red to warm brown to black. Male merfolk have similar growths extending down from their cheekbones." - D&D 5e Wiki
12. Ochre jelly: "ochre jelly resembles a giant amoeba, consisting of a thick, porous, golden sludge. It lurks in dungeons, slowly sludging its way along floors, walls and ceilings alike, under doors and through cracks, looking for victims. When it finds them, it extends, latches onto them, and then proceeds to engulf and constrict them. The ochre jelly reproduces asexually, and can sometimes be found with several of its divided offspring. They cannot speak, and are neutral in alignment." - Wiki
13. Plesiosaurus: "This predatory marine reptile and cousin to the dinosaurs attacks any creature it encounters. Its long, flexible neck lets it twist in any direction to deliver a powerful bite." - Aide D&D
14. Rug of smothering: "an animated carpet capable of smothering other creatures to death." - Critical Role Wiki
15. Will-o'-wisp: " malicious creatures that appeared as torches or lanterns seen floating through swamps." - The Forgotten Realms Wiki
