tl;dr:
Take ord() value of each emoji, cut off first number, divide the remaining 4 numbers into two groups. Filter away all that are less than 32, and decode as ASCII. Align remaining ASCII art.

```python3
# Here's the ord() value of all the emojis, instead of messing up the writeup with unprintable characters
