Dreamy Bowser

Dreamy Bowser is rainbow-colored and has Dream Stone-like crystals on his head and chest.

On the balcony of Neo Bowser Castle, Bowser appears in front of a caged Princess Peach and reveals to the Mario Bros., Starlow and Dreambert his intentions with the Dream Stone. He begins to use it to erase the Mario Bros. from existence, however, before he can do a single thing, Starlow and Peach use "the power of good thoughts" to interrupt his attack and destroy the Dream Stone upon Dreambert's insistence. However, Bowser, however, knowing that he can still destroy the brothers, inhales the Dream Stone shards. Although regretting inhaling it (mentioning that the taste of the Dream Stone is "gross") and starting to cough and splutter, the Dream Stone's remains possess Bowser, turning him into Dreamy Bowser. With his new unlimited power and extra strength from the Dream Stone, Dreamy Bowser reveals his true intentions to kidnap Peach for himself, take over Pi'illo Island and eventually the entire world. The empowered Koopa King engages Mario and Luigi in combat.

Upon defeat, Dreamy Bowser explosively expels the remains of the Dream Stone from his body and reverts to his normal form, abit dazed from his power and weakened. The Mario Bros. then immediately take him out with their Hammers, sending him flying and freeing Peach from her prison.

Rainbow Flame: Dreamy Bowser will launch a bunch of rainbow flames at Mario and Luigi. Dreamy Bowser will then create a clone to help out in the attack, forcing Mario and Luigi to jump even faster in order to dodge it.
Dreamy Shy Guy Airtub: Dreamy Bowser will send out a large Dreamy Shy Guy Airtub that will chase only Luigi. Mario will be on the airtub itself and hammer away the Dreamy Shy Guys and attack the airtub itself with his hammer.
Bro Grab/Bro Throw: Dreamy Bowser will grab either Mario or Luigi and then tosses that bro away. Mario or Luigi must catch up to the other bro and catch him. If not, that bro will continue to take damage until they are caught or lose all of their HP.
Hammer: Dreamy Bowser will summon a large hammer and then will flip a coin. If it lands on the "M", he will attack Mario and if it's "L", he will attack Luigi. Be alert that as soon the targeted bro deflects the attack, Dreamy Bowser will attack the other bro with the hammer.
Minion Attack/Heal: Dreamy Bowser will summon a horde of Dreamy enemies and they will start to charge at Mario and Luigi. Dreamy Bowser will also use this opportunity to heal himself until all of the enemies are defeated. It should be noted that sometimes, Dreamy Bowser will slam the ground, sending a shockwave that not only damages Mario and Luigi, but his minions as well.
Rainbow Fire Stream: Dreamy Bowser will start to charge at Mario and Luigi and launch three streams of rainbow fire at them. Mario and Luigi must jump over this or take heavy damage. If Mario and Luigi dodge the fire stream, Dreamy Bowser will then stomp the ground causing a shockwave to head after the Bros. This is Dreamy Bowser's strongest attack.

BWA HA HA HA!

Late at night I'm always dreaming
Of my might and of my scheming
Failures near had me believing
They were all pretend

Now within this midnight hour
Now I glow with starlight power
Now shall blossom Bowser's flower!
Now you'll meet your end!
Now my dream's reality!
Now bow down to the Koopa King!

Die! Drown now in sleep
Where all the nightmares lie beneath
I, the king of dreams
Will now, forever, reign supreme!
Conquest I bring
Power I sing

Years of fighting, lost to plumbers
Was I weaker? Was I dumber?
Now at last I have your number!
Now I fix the odds!
Everything I dreamed of - mine!
The dreams and starlight now aligned!
The Koopa King at last divine!
Now kneel down to your god!

Now my dream's reality!
Now bow down to the Koopa King!

Die! Drown in sleep

Where all the nightmares lie beneath

I, the king of dreams

Will now, forever, reign supreme!

Trumpets sound and bells will ring
Clashing with the Koopa King!
Now, here we stand
At adventure's end!

Neo Bowser Castle: In Dream Team, it does not appear until the middle of the game, where it appears floating high above Pi'illo Island, until it is grounded and lands in the east, north of Somnom Woods and east of Mount Pajamaja. It can be reached by traveling north in the area between Mushrise Park and Somnom Woods.
