Some of her emotions can also assist her in ways. When she triggers the Joy emoticon, Princess Peach becomes very happy and becomes enveloped in a powerful cyclone with musical notes. This cyclone allows her to fly, gust away fogs and clouds, turn windmills, slow down her falls (as if she couldn't do that already lol), and so forth with its winds. The cyclone is rather small and not really destructive, but it can repel weaker enemies.
During a state of Gloom, Princess Peach will cry. This will increase her speed dramatically, and will also allow her to jump higher and farther. And that's not to mention the endless gallons of crocodile tears that will come fountaining uncontrollably from her eyes. The thick streams rivers of tears can be redirected, and can also be used to repel enemies, extinguish fires, clean filthy places, etc. Sparkles will always appear wherever the tear rivers touch.
While Enraged, Peach's entire body will be engulfed in a huge blaze. The flames make her invincible, make it harder for her foes to reach her, will burn enemies and other objects nearby, yet the flames do not consume Peach herself. While aflame, she can ignite/light things up, melt snow or ice, and light up dark places. However, being on fire will slow her down tremendously and greatly impede her reflexes and agility. It also adds a lot to her weight (but her appearance won't show it), which forces her body to fall faster and will cause tremors whenever she lands.
When Princess Peach is Calm, she will become delighted and a bubble will appear and surround her. This field will gradually cure any wounds she may have received, and will also block out water, harmful gases, some levels of radiation, etc. from entering. The bubble's protection allows her to breathe and survive underwater, in outer space, and in other places she otherwise would not be able to. The bubble will continually provide oxygen for her as long as it remains, however it will instantly pop and vanish once something hazardous touches it. She can still move and take actions while the bubble is surrounding her, and can also consume more ME (Mood Energy) to expand her bubble so others can fit inside as well.
*It should be noted that these emoticon abilities are all controlled voluntarily (which is the reason why she is able to turn them on and off so instantly), so she will not accidentally trigger one of them with any unprecedented feelings. Her Mood Energy (ME) is what she uses to activate these abilities, and it is also her limit to how long she can use them. Peach's ME can be replenished in two ways, one being simply waiting for her ME powers to recharge gradually through time and rest. Secondly, she can absorb smaller and weaker foes that she catches with Perry.
