To The New Days, Players can reminisce through fan’s favorite SpongeBob moments as the game draws upon ‘The 10 Happiest Moments of SpongeBob’s Life’ they are called Jellyfishing With Patrick, Meeting Sandy Cheeks, Pretending To Be Tuff With Patrick, Becoming A Fry Cook, Santa Santa Santa!!!, Meeting Mermaidman And Barnacle Boy, Squidward's First Yummy Krabby Patty, 24 Hours Of Fun At The Krusty Krab With Squidward, Kara-tay With Sandy ,and the final boss level is, Hey, That's Not Your Formula Plankton! And hilarious story elements from the animated television series. In multiplayer mode, players can play as SpongeBob or with a friend playing as Plankton throughout the entire game on both the Wii and Xbox 360 platforms. The power ups in the game can help SpongeBob during one of his happiest moments here are the power ups. These are based on Spongebob's skill's the spatula slam and the spin slap and the cannon shot. The hammer makes Patrick appear and use SpongeBob as a mallet. The Gloves with halves of his face on them makes Sandy appear and use SpongeBob as a pair of Karate Gloves and spins around until the time limit goes down to 0. Clarinet makes Squidward appear and use SpongeBob as a Clarinet to shoot music notes at robots, which turns SpongeBob into a stronger version of himself .
Jump into a Shower (or in the house, the bathtub.) to invest SpongeBob with water. Also when you fill yourself with water in levels you can spray the water out on platforms that look like sponges spray them to make them bigger. There is also a Downtown Bikini Bottom stage and Krusty Krab stage included only in the DS and PSP versions and a Mr. Krabs power up exclusive to the DS version.
Some of the game's stages resemble the ones from Battle For Bikini Bottom. (Jellyfish Fields, Kelp Forest, Mermalair and Rock Bottom.) The game also includes Tikis and Robots just like Battle For Bikini Bottom.
The music used in this game are recycled from SpongeBob episodes and two SpongeBob games. (Battle For Bikini Bottom and SpongeBob Movie.)
Ironically enough, the stages take place in events of SpongeBob's life that are similar to events in the SpongeBob episodes. (Such as faking a fight to get in the Salty Spittoon and the story of the Hash-Slinging Slasher.)
In the game defeating the PatBot takes place at night while the episode it’s based on takes place in the day, although the DS version of it takes place in day.
The boxes around the level you can teleport to when you complete the level resembles the box from Idiot Box. They also are similar to the boxes in BFBB and The Spongebob Movie Game.
Prawn, the mini-boss in the Mermalair from Battle for Bikini Bottom appears in the Truth or Square Mermalair frozen in tartar sauce exactly as he appears when defeated in Battle for Bikini Bottom (except bigger and SpongeBob said he was Man Ray by mistake and realizes he was Prawn, but calls him Mr. Shrimp).
Each platform cover has a different SpongeBob face.
Robo Squidward, the cut boss from BFBB, appears as a boss in Squidward's First Yummy Krabby Patty.
