[Update] Monsters Ate My Birthday Cake walkthrough - secrets, side quests, costumes, and monsters
Updated on September 8th, at 10:06: Monsters Ate My Birthday Cake was recently patched and updated, which fixed a few bugs that would stop you from finishing the game.

With those nuisance glitches out of the way, we have been able to finish up this guide. That includes solutions for levels 3-2C and 4-10, and the last three messages in bottles (below).

With this guide you can now get three stars on every level, and unlock every achievement on Game Center for a total of 450 points. Your parents will be so proud.


Monsters Ate My Birthday Cake follows Niko on his sweet and sickly saga of vengeance against the Boogins who nicked his yummy dessert.

He, and a bunch of significantly more friendly monsters, will traipse across Gogapoe Island, solving logic puzzles and winning back his cake: slice by delicious slice.

In this complete guide, we'll teach you how to beat every mission, complete all the side-quests, find all the costumes, and more.

Main missions

These pages feature three-star solutions for each puzzle, as well as step-by-step guides to the sidequests you must finish to unlock bonus levels.

Outfits

Niko can change costumes to unlock new powers - some of which are needed to complete certain quests. Other costumes invoke more subtle changes, or are purely cosmetic.

Niko's PJs - This nightwear suit can be bought from any shop in the game for 15 coins. It doesn't give you any special powers. Sneako-Niko Outfit - This fetching ninja costume can be bought from any shop in the game for 15 coins. It doesn't do anything when you double tap Niko. Finn Outfit - You can get this Adventure Time suit by sneaking into an abandoned house in Gogapoe Village. Gaming system

Walk through one of the bushes behind Lizzy and her badger, and enter this secret house. Inside is a key, which opens a nearby treasure chest. You'll find a game boy inside which lets you buy the Finn suit for 15 coins.

Gnome Outfit - This silly suit doubles the value of any coin that Niko and his monster friends pick up. Here's how to find it. Sweat pepper

After visiting level 4-K, talk to Hugo to get the sweat pepper.

Krackles

Give it Krackles in 4-K to get a cricket.

Fishermen cricket

Give the insect to the fishermen on the dock in Gogapoe Island to get a red mushroom. Now you can buy the gnome outfit from any shop for 30 coins.

Badger Suit

Give the honey to Izzy and the badger will cough up a hairball. With this, you can now buy the badger suit from any shop for 30 coins.

Return to the village and give the dead battery to Nibbins (in the house near Fia and Astrid). He'll charge it up.
