Egg-Glue-Spoon is the sixth stage in Autumm = Sports Day!
The battle begins with Le'boin, Sir Seal, One Horn, and Pigge Back. As the latter enemies are slightly easier to defeat, they will be spawned slowly throughout battle to help you increase your Cat Wallet.
Le'boin can be quite annoying in this stage as he's quite buffed and can wipe out your enemies with his good range, but not to worry. Meatshield well, bring along anti-Reds and your ranged attackers, and all should be fine. If you have Ramen Cat then this stage is a breeze.
