Angry Birds Birdday Party Secret Cake Achievement Walkthrough

Here is our Angry Birds Birdday Party (Birthday Party) walkthrough video that will help you unlock the Secret Cake Achievement found level 18-15. If you have a different method for obtaining this that you think is easier feel free to leave a comment below explaining your strategy. The steps for obtaining the secret cake achievement are as follows:

  1. Use the Yellow Bird or the Orange Bird to hit the TNT and destroy the donut on the far right hand side. You need to leave some debris above the TNT that is adjacent to the piece of cake. When you complete the other steps this debris will hopefully fall down and blow up the TNT.
  2. Destroy the treasure chest that appears BEHIND the slingshot platform with White Bird.
  3. If no debris falls through and you have an opening, you can still try to fling the Boomerang Bird into the gap to hit the TNT and get the cake! This won’t be an easy shot.

Just Try a lot and find out how to shoot your bird and use ability when and where its hard but it’s a way

By John

What’s the point of getting the secret cake? Does it get you an extra level or golden egg? If it does, I haven’t seen where it does that yet.

It’s necessary for the 60th achievement. Otherwise, it’s just a lot of fun.

By sarah

I’ve gotten the cake multiple times but never see any achievement notice or big cake pop up.

Rank: Sling God with 32120 points
By AMslimfordy (@amslimfordy)

Both of them (the achievement and the big cake) only show up the 1st time. Check your achievements in GameCenter to see if you already got it. The achievement appears at the bottom of the list.

By sarah

It just showed up in Game Center- guess I missed it the first time!

Same here. I was able to blow the TNT and the donut in one shot, then the chest showed up- hit that, and then nothing. This is the second time I have had a bug where I can’t get a response. Bummer.

There’s 1 more step. You need to actually get the slice of cake. Trigger the final TNT.

By Digs

how do you get achievments?

Rank: Sling God with 32120 points
By AMslimfordy (@amslimfordy)

Achievements are only available for iOS devices with GameCenter.

By kkendel

So, for Androiders it’s just a “Hey, cool. Meh.”?

Meh. :/

Should’ve been a secret level.

Rank: Sling God with 32120 points
By AMslimfordy (@amslimfordy)

It’s not a whole lot more than that for iOS users. Maybe in the future it will be a “Golden Egg” level.

i didn’t get the donut, just flung the white bird backwards (no chest there, just some balloons) and got the achievement too (unless something colapsed in the end and hit the donut after it wasn’t on the screen anymore, but i doubt that, people should try it wthout the donut

Rank: Sling God with 32120 points
By AMslimfordy (@amslimfordy)

I don’t believe it is possible without the donut. What were you previous 2 shots (Yellow and Orange)? If you just flung them into the main structure, there is a high probability that you triggered the bottom TNT anyways.

Edit: OK, you can indeed break the chest without it being there. I’ve confirmed it. However, I don’t believe this is easier.
1) That’s a very difficult shot.
2) You still need to get something to go down the hole created.

You might as well just cause damage to the main structure and pop the donut.

By Overlord G

you can take the yellow bird and knock over the top stone block on the far right. That block will then hit the donut and r eal the treasure chest

By verbaldata

I had balloons behind the slingshot, too — not a chest. Also when you say “donut” are you referring to the cave-like opening underneath? It’s just a bit confusing: get the donut, get the cake (and there are donuts in Angry Birds sometimes), but I gather that “get the donut” in this context means to ignite the TNT inside the cave. I’m not sure I did that, either. I got the upper TNT but not the lower, but I then shot the white bird backwards anyway and got the achievement to my surprise. And I definitely saw balloons but not a chest.

Sometimes it takes time for achievements to appear in GameCenter. You could try logging out and back in to GameCenter manually.

By Elaine

Have gotten the treasure chest twice. Direct hit with wb egg. Still no cake! I’m missing 1 star,MIS that my problem?

Rank: Sling God with 32120 points
By AMslimfordy (@amslimfordy)

You are missing the last piece of the puzzle: You need to hit the (now-exposed) TNT in the middle of the level. Fuji got a bit “lucky” in his shot, and is actually a bit upset about it since he wanted to demonstrate this last shot with the Boomerang Bird.

By Elaine

Thanks. Got it! Now for that 3rd star on 18-12.

By akari

omg i got the cake but not the achievement T___T most of the achievement names changed to japanese after the update …maybe thats the problem?…:(

May want to go check either your iPhone or GameCenter settings.

The achievement may take a little time to appear.

By DB

Once I get the cake, what happens? Is there a bonus level? I don’t have an gamecenter because i’m on Android.

Rank: Sling God with 32120 points

Just a fun thing to do. There’s no bonus level or anything.

Another possibility for getting the TNT when the hole opens up is to drop the egg/bomb from the right height onto the Treasure Chest – the white bird then shoots up and off to the right and will come down (eventually) through the hole onto the TNT!

Oh and you answer a lot of questions so can you answer this one the first time I thought I got it but I did not hit the TNT so I did not get anything but when I tried again the treasure chest was gone but the cake was still there and I do not have the achievement in game center and I do not need to update anything.

What does getting the piece of cake achievement do? I got it and dont see anything different. It just said congratulations you’ve earned….. Is there another level or something I am missing?

on iphones and ipads you get an achievement through gamecenter: cakemonger.
That’s about it.

Correct; no bonus levels for obtaining it. Just a fun tidbit.

Yes and about the feathers… only for iOS Android T-Mobile and Goohle Chrome but i heard about the Mighty Eagle coming to full Android soon thru GetJar

By Bill

PC Version. I hate to appear dense, but can the cake achievement be obtained one time only? I open the hole, and drop the stones on the TNT, everything blows, the slice of cake disappears, but doesn’t come up on the screen like it did the first time.

Rank: Sling God with 32120 points
By AMslimfordy (@amslimfordy)

Only once, regardless of platform

Thanks for clearing up that question. I saw the treasure chest and didn’t know what was going on,since I hadn’t read this page yet. Now it makes sense. Maybe someday I will make the jump to Apple and get all of these neat achievements and extras :). Still so much fun, even without the ME and achievements.
