The winroom of this sub-area is themed on the birthday party of UDG1's anniversary. It consists of a birthday cake that represents all 3 cakes present in the sub-area as well as all the creators/members during the development of Sub-Area 1. Hot Strawberry is the second cake and is based of a strawberry cake consisting of many strawberries as well as ribbons, cream and shards. It also features a big hot air balloon tied to a big red telephone at the top of the cake. This cake was meant to represent the mid era of UDG1, where events started to appear in the game. Thus, the red telephone representing the telephone section in Winter Event 2020. The tasks/layers in this cake are a bit more complicated compared to the simple Sweet Vanilla and having a higher difficulty compared to it. This cake also has three tasks, with difficulties ranging from 2.8 ~ 5.9. This cake is considered to be the middle of the three cakes in terms of difficulties. In Sub-Area 1, tasks are represented as Layers. The following creators are creators who built the problem/puzzle of the layer. All of the creators has contributed to the design of each layer. Sweet Vanilla is the first cake and is based of a vanilla based fruit cake. It's design is rather simple as it is meant to reference the early era of UDG1. The top of the cake lies a room that is reminiscent to the old rooms of UDG1. Thus, the infamous sequence room was chosen as the puzzle of Layer 3. This cake is designed to be the easiest out of the three.

Searching the confirmers, the player will arrive at an amusement ride company, Technical Park. Entering it into the UTB will confirm that it is what the player is looking for. Decrypting 'FIDDLE AMONGST THE CAT' using the conversion table gives 'DKHHQL WEOIZFM MJL AWM' as the decrypted text. Upon opening the document for UTB tag 'CROSS', the player is greeted with a crossword which they will need to solve with the hints on the floor. Country: There is an Italian flag in the room, which is explicitly said to be the country of origin for the company. Once the player has gone up the stairs, they will be greeted with another door that serves as a transition to the next layer. The code is the layer that the player is on, which is 2.

Next, the decryption table. The player needs to substitute the hints in the decryption table with letters from the answer they got. For example, the 1st letter of 3 is referring to the 1st letter of the 3rd crossword word, which should be A.

Encoding Technical Park in T9 gives 83246422507275 as the answer. Removing all numbers larger than 7 and all 0s gives 324642257275 as the code, which the player will need to enter on the telephone above. While the player may try to research on the wiki with the information, they will actually get nowhere with the vague information.
