Bubble Spray (named Mercury Bubbles Blast in the original English dub) is the very first attack used by Sailor Mercury. It was primarily a defensive attack, involving the formation of fog, which reduced overall visibility in the area. It also lowered the temperature of the area by a few degrees.
In Episode 45, Sailor Mercury used Bubble Spray to provide limited protection for herself against intense heat and flames. Bubble Spray was also one of the attacks used by Sailor Mercury in the video games Pretty Soldier Sailor Moon S and Sailor Moon: Another Story. In Another Story,it decreased the attack power of the targeted enemy, causing them to do less damage to the party. To do the attack in the anime, video games, Mercury gathers water in her cupped hands, twirls around with it, and then releases it this makes a fog appear, while in the video games, bubbles fly at the enemy.
- This attack, Bubble Spray Freezing, Akuryo Taisan, and Moony Moony Love-Me Moon Chain are the only attacks in the Japanese dub not completely said in English.
- It was her primary attack used in the first season of the original anime. It eventually became much stronger and more effective with Bubble Spray Freeze (Mercury Ice Bubbles Freeze) and Shine Aqua Illusion.
- "Sabão" is the Portuguese word for soap. It is a Portuguese loanword in the Japanese language.
- In most episodes, an animation mistake can often be seen where in one frame, Sailor Mercury's left glove turns skin color briefly before returning to its normal white color. In the Sailor Moon S movie, when Sailor Mercury used this attack to stop one of Princess Kaguya's Snow Dancers, this animation mistake was corrected.
- Even though it was originally called "Mercury Bubbles Blast" in the English dub, this attack was renamed "Bubble Spray" in ADV's remastered DVD boxset and Viz Media's dub.
- In the Dic dubbed versions of episodes 72 and 73 this attack was mistakenly called "Mercury Ice Storm Blast". This was the name DiC used for Shine Aqua Illusion.
- The attack is usually misread as "Shabon Spray" due to Ami's pronunciation in the original anime.
