Dreamtails  
The third issue included clips with locks of false hair called Dreamtails. The bottom corner says "FREE Dreamtail inside. Collect more then one for styling fun!" Dreamtails had pink clips with either blue, white or purple glow in the dark hair. I'm not sure if Bucky was released with a Dreamtail.

Versions I've seen: All known releases (Dreampoints, red Record, and white or purple Dreamtail). 
Dolls from these releases seem to be the same, only the bonuses and packaging differ.

Dream Gazer is truly a mysterious Moondreamer, she has been seen with a few variations. The Dreamtail version sometimes has the star around her eye and sometimes not. I have even heard of a version where the star was purple rather then the usual brown but I don't know which version it was. The Dreampoints version is the only one that came wearing her infamous head disk, but the other versions included it inside the box where it can't be seen. The comb that came with her Dreamtail version was pink. (Thanks to Brian for some of this info.)

(Missing his shoes, and the ties for his vest are gone. With original hairstyle.)  
   
Bucky Buckaroo has short, straight blond hair, blue eyes and freckles. He has his own pose. He came with a green circle shaped dream crystal necklace, a blue comb and a clear blue stand. Wears a gold jump-suit, blue vest, and yellow lace style shoes.  

Versions I've seen: Record. This version seems to be the most common for him.

(Missing her headband and shoes. Hair is almost right.)  
   
Celeste has wavy lavender hair and pink eyes, she's looking up. I don't know if she came with a Dream Crystal necklace, but she does have a blue comb, a light blue wand, and a yellow moon barrette. She wears a long blue dress with clear cape and sash, silver headband with butterfly shape, blue tights, and blue crescent moon style shoes. It should be noted that hers are the only clothes that don't have any glowing bits, except her shoes.  
 
 
Galaxia is a vehicle style figure. She is a large pink dragon with purple hair and an open bench in her back big enough to sit two or three dolls. She came with a yellow star barrette, a starred necklace, and a ribbon to act as reins. 

Versions I've seen: I have only seen this set MIB once. It was issued later then the other figures, so it's probable it only had one release. I don't know enough about this one to say for sure, but one thing is sure; it's very rare. That alone would imply it had fewer releases then the others. 
 

Versions I've seen: As far as I know, there was only one issue of this set, yet it seems to be one of the most common MIB.

They came with a pink flower patterned dream crystal necklace, a blue hairpick and a clear blue stand.  Blinky has straight pink hair in two pigtails to the sides. She shares a pose with Bitsy. She wears a pink dress, silver headband with moon shape, white and silver tights, and blue shoes. Ursa is a white plastic bear figure with a moulded on star necklace and saddle blanket. She came with a blue patterned saddle.  

Versions I've seen: As far as I know, there was only one issue of this set, yet it seems to be one of the most common MIB.

Each Snoozer had their own pose. Dozer is pink with blue pyjamas and came with earmuffs and a wand, Stardust is purple with yellow pyjamas and came with a cape and sand bucket, Stumbles is blue with pink pyjamas and came with a hat and glasses.  

Versions I've seen: Dozer ~ two issues with the only difference being the packaging, one with the accessories to the side and one with the accessories on him. His prototype has him coloured blue, but as far as I have seen he was not issued this colour. Stardust ~ two issues with the only difference being the packaging, one with the accessories to the side and one with the accessories on him. Stumbles ~ two confirmed issues with the only difference being the packaging, he's facing left in one and right in the other. I have also seen a loose Stumbles coloured pink like his prototype doll, and a blurry MOC photo in which he kinda looks pink, so it's possible there was an issue with him coloured this way. 
  
There was also a plush Stumbles available. His accessories were attached and included his hat and glasses and also a yellow pouch over his back. (The photo is of the prototype, the only difference is that the store release didn't have the lenses of his glasses filled in. Of course, Stardust didn't come in the pouch with him.)

(Missing her Yawny.)  
   
Evil Scowlene is aqua with curly neon yellow hair. She came with a nightmare crystal necklace, a neon yellow hairpick, a blue Yawny hair clip and a stand. She wears a green and purple robe with attached purple mesh cape, and purple fuzzy slippers.
 
Versions I've seen: As far as I know, she was only issued once.

The Sleep Creeps each had a unique pose. Creaky is blue with purple trim and came with green sandals, Shiner is purple with red trim and came with a blue flashlight, and Squawker is pink with blue trim and had a blue megaphone.
