Kirby Canvas Curse

I like this one a lot, actually!

Drawcia is one of the three bosses to STRIP during a battle. The other ones are King Dedede (who flexes his clothes off in Kirby: Star Allies) Clawroline (removing her cape and top hat in Kirby and the Forgotten Land).

Coincidentally, King Dedede is the only one out of these three that doesn't strip in their debut game.
Drawcia is the only one out of these three to do so in the 2000's.

Several bosses from previous Kirby games were intended to be playable characters in early development of Kirby: Canvas Curse, including Lololo & Lalala, Nightmare, Dark Matter and Zero. Concept art of these bosses as balls can be found in the 20th Anniversary Kirby Pupupu Encyclopedia (page 125), but they are not present in the final game.
Kirby: Canvas Curse is the first video game in the Kirby series that introduced the Soul Boss - Drawcia Soul. The main series would later introduce even more Soul Bosses.
In Kirby Battle Royale, one of Whip Kirby's Headgears is the Gymnastics Leotard. This could be a reference to the Japanese commercial for Kirby: Canvas Curse, which features a female gymnastics athlete guiding the Kirby ball's movement with her ribbon.
Most of the themes in this game are remixes of themes from earlier games in the series.
Kirby: Canvas Curse holds the distinction of being the Kirby game released closest to the launch of its target system. It was released in Japan on March 24, 2005, 124 days after the launch of the Nintendo DS, whereas in North America, it was released on June 13, 2005, 205 days after the DS' launch in that region.

Kirby: Canvas Curse is also the only Kirby game to be released within a year of their target console's launch in both North America and Japan.

Kirby: Canvas Curse is the only Kirby game to receive a commercial produced by KCL Productions, a mascot costume manufacturer. In the commercial, Kirby and a large, walking finger named Finger go on an adventure through a city before following a rainbow path.

Much of the commercial was filmed on several parts of the backlot in Universal Studios Hollywood, which recieved its own Super Nintendo World expansion on February 17, 2023. The scene where Finger makes a bridge across the manhole for Kirby to walk on was filmed on Brownstone Street. The park where Finger pushes Kirby on a swing was filmed in front of Courthouse Square. The rainbow that leads to the bridge where Kirby and Finger walk across near the end is the Collapsing Bridge.

This is the first game since Kirby 64: The Crystal Shards where abilities do not grant hats to Kirby.
During the credits, the player can cause the Portraits of the characters to fall by simply tapping them with the stylus.
All of the first letters in the names of the levels with the exception of The World of Drawcia form an acronym (Reddy Land, Arange Gorge, Iello Adventure, Neo Greo, Bloo Hills, Omarine Zone, and Wonder Lilane), which spells out "RAINBOW."
The title screen changes color from white to turquoise if the player has a 100% save file.
Kirby: Canvas Curse contains a built-in PictoChat search function. When enabled, the player's Nintendo DS will look for other Nintendo DS systems that have activated PictoChat while still allowing the player to play Kirby: Canvas Curse; an orange icon will appear in the top-left corner of the screen if the search is successful. If the player taps this icon, the Nintendo DS will power down, reboot, and activate PictoChat.
On September 15, 2005, Nintendo allowed users to receive a special pink DS stylus if they registered the game on the Nintendo website. This stylus came as a physical extra with all Japanese retail copies of the game, titled "Kirby Pink."
