Meanwhile, King Dedede and Escargoon are sunbathing too. Escargoon looks up, only to see that King Dedede is suffering from a massive sunburn. After seeking advice from Customer Service, he tells them about the effects of UV rays and notifies them of their products which Dedede can sell to the Cappies. Shortly after this event, Escargoon makes a health warning on Channel DDD about the sun and UV rays. The warning ends with him and Dedede promoting the use of sunscreen and the Escar-Cool 5000 Air Conditioner. Later, Tuff, Kirby and Tiff sneak outside to play, while the rest of Cappy Town are in fear of the sun.
Kirby and his friends are revealed to be playing a game, when Tiff arrives and informs them that they all have sunburns. She then takes note that the sun itself has been acting weird lately. Later on, Lady Like thinks of an odd idea; Sleeping in daytime! Soon, all of Cappy Town catches wind of the idea and night becomes the new day. Meta Knight, on a grocery trip, warns Tiff that either the sun is getting stronger, or the planet is getting weaker. Kirby and co are playing football in the daytime; Fololo and Falala find the duo and tells them to come to the castle; There, they find out that Tiff and Co. are making a hot air balloon! The plan was that they fly up to the sky and find out what is causing the heatwave. Dedede notices the balloon and Customer Service teaches them about the Ozone Layer and the hole in it. Meta Knight tosses a canister from the balloon which lands in Cappy Town containing a note that warns the Cappies about the danger and to check their air conditioners. Once they do, they find out that the air conditioners were rigged to destroy the Ozone Layer! Meanwhile, Kirby is sent to fix the hole via Warpstar, fighting a newly formed Ozone Monster in the process. Unfortunately, the UV rays are too strong for him, so TIff and Tuff throw the burner from the balloon at Kirby, causing him to transform into Jet Kirby. Kirby attempts to fight the monster once more, but the monster proves too much for him again. During the battle, Lady Like tells Sir Ebrum that he should search for Dedede and ask for his help against the Ozone Monster. When Sir Ebrum finds King Dedede, Dedede fires a cannon at Kirby, and the cannonball is hurled at Kirby. Luckily, he inhales it to become Bomb Kirby. Kirby tosses bombs at the monster and defeats it, causing the Ozone Layer to revert to normal. Later, Kirby and friends are relaxing at the beach, without needing to worry about getting sunburned, while King Dedede and Escargoon had buried themselves to avoided getting sunburned.

Changes in the Dub
The tan coloring on the affected characters skin, except Kirby's, was changed from brown to reddish orange, probably to prevent a controversy on racism.
The cover on Sir Ebrum's and Lady Like's photo album shows a heart with a strange design on the heart. The design on the heart was removed from the English dub for unknown reasons.
The scene where King Dedede shows his face in front of the television after he uses his sunblock to show it works well was removed from the English dub for unknown reasons.
