There are 12 achievements with a total of 200 points. | |||
![]() | Quest Complete | 5 | |
| Complete a Quest Mode game | |||
| So to start off let me tell you how to play. There are a total of 9 levels, Krusty Krab 1/2/3, Dutchmen's Ship 1/2/3, and Atlantis 1/2/3. To beat a level you have to collect 99 underpants before the time runs out. To add more time to the clock collect underpants, collect medals, and kill jellyfish. There are numerous ways to kill jellyfish; push For the achievement Quest Complete, you'll have to beat any level in the quest. Seeing as how when you start only Krusty Krab 1 is open, there's only one way to get this achievement, beat the level! Collect all 99 underpants and smile as the achievement unlocks. | |||
![]() | Fast Track | 30 | |
| Complete all Time Trial levels | |||
| You will have find all 99 underpants in the time given to beat the time trial. In time trials you will no longer get extra time for each underpants you get. You need to beat all 9 levels. The first and second levels in each stage give you 3:00 to collect the pants, but the third levels only give you 2:40. Levels 1/2 shouldn't be too hard, but the 3s are a killer. Remember pant locations and strategies for the best route. Hardest part is not getting shocked (as it blows 3-5 seconds) and getting underpants from jellyfish. | |||
![]() | Party Animal | 15 | |
| Win a multiplayer game | |||
| Because this achievement is not a "online" multiplayer game you're more than welcome to do this over local play with a second controller. During a multiplayer game you need to collect the most pants and also have the least amount of tags. Just remember to jump and body slam people. | |||
![]() | Jellyfisher | 15 | |
| Defeat 100 Jellyfish! | |||
| This one is really easy and you should get this one without even going for it. Just remember: | |||
![]() | SpongeBob ThousandPants | 20 | |
| Collect 1000 underpants! | |||
| This achievement is impossible not to obtain if you go for either the Masterful or Prospector achievement. Playing through the quest once will net you 891 underpants, just play an additional 2 levels and you'll get the achievement. | |||
![]() | Wide Awake! | 5 | |
| Break out of a Stun! | |||
When you get stunned by an electrified jellyfish move the left thumb stick left and right as fast as you can to break out and if you do it fast enough this one will unlock. | |||
![]() | No Pants! | 10 | |
| No pants in a multiplayer game! | |||
| Because this achievement is not a "online" multiplayer game you're more than welcome to do this over local play with a second controller. Start any kind of multiplayer match (because they all involve pants) and just sit still and wait for the game to end. Watch out though some pants fall randomly and might land on you, if this happens have one of the other players hit you until you drop them. End the level without pants and the achievement's yours. | |||
![]() | It | 15 | |
| Be ‘it’ for 50 seconds! | |||
| Because this achievement is not a "online" multiplayer game you're more than welcome to do this over local play with a second controller. Choose a game of tag and get ready! Have the person who's not going for the achievement go to the person who is and tag them The shortest amount of time to play is 3:00 so you can easy get three people the achievement in a single boosting match. | |||
![]() | Superhero! | 15 | |
| Use Super Moves 25 times! | |||
| Your special move bar (the blue bar above your health bubbles) fills by doing the following: killing jellyfish, collecting underpants, collecting orbs, and breaking items. Once it's full it'll start flashing and you'll be ready to activate it. Simply press | |||
![]() | Masterful | 30 | |
| Beat Quest mode with all 5 characters | |||
| It's really easy but just takes some time. In order to beat with every character you will need to have beaten the game once already to have unlocked Plankton. Best way to keep track is to do something like this: Character 1 - quest & bronze Character 2 - quest & silver Character 3 - quest & gold Character 4 - quest Character 5 - quest | |||
![]() | Clumsy! | 10 | |
| Fall out of the level 50 times | |||
| Can be done only on Atlantis or the Dutchmen's Ship. At the bottom of these stages there are gaps which you can fall through. Just do this 50 times and you will get the achievement. Personally I found it easiest to start Dutchmen's Ship 1, immediately head right, up the stair and onto the platform. Break the platform and walk off. Once you fall you'll respawn right next to the platform. Without collecting health orbs you can fall up to 5 times. Just rise and repeat until the achievement's yours. | |||
![]() | Prospector | 30 | |
| Collect all the Gold Medals | |||
| For this achievement you'll have to beat each level will collecting 5 bronze medals. Then you'll have to beat the same levels again, but this time going for silver medals (instead of just floating like the bronze, the silver medals will be carried by jellyfish, kill the jellyfish like they had underpants and collect). Once you get all the silvers, play all the levels again for some gold! The gold medals are hidden within breakable objects that can only be broken by super attacks | |||
