The challenge page gave a long string of emoji characters: 🎉🎊🎉🎉🎊🎊🎉🎉🎉🎊🎉🎉🎊🎊🎊🎊🎉🎊🎉🎉🎊🎊🎊🎊🎉🎊🎉🎉🎊🎉🎊🎊🎉🎊🎉🎊🎉🎉🎊🎊🎉🎊🎉🎊🎊🎊🎊🎊🎉🎊🎉🎉🎊🎊🎉🎉🎉🎊🎉🎉🎊🎉🎉🎊🎉🎊🎉🎉🎊🎉🎊🎊🎉🎊🎉🎉🎉🎊🎉🎊🎉🎊🎉🎊🎊🎊🎊🎊🎉🎊🎉🎉🎉🎉🎊🎉🎉🎊🎉🎉🎊🎉🎉🎊🎉🎊🎉🎉🎊🎊🎊🎉🎉🎊🎉🎉🎉🎉🎉🎊🎉🎊🎉🎊🎉🎉🎊🎉🎉🎊🎉🎊🎊🎉🎉🎊🎉🎊🎉🎊🎊🎊🎊🎊🎉🎊🎉🎊🎉🎊🎉🎉🎉🎊🎉🎉🎊🎊🎊🎊🎉🎊🎉🎊🎊🎊🎊🎊🎉🎊🎉🎉🎊🎊🎉🎊🎉🎊🎉🎉🎉🎊🎉🎊

Looking at this string, you can see that there are only two different characters that are used. What else uses only two characters? That’s right, binary. If we swap 🎊 for 1 and 🎉 for 0, we get the following: 0100110001001111010011110100101101010011010111110100110001001001010010110100010101011111010000100100100101001110010000010101001001011001010111110101010001001111010111110100110101000101.

By converting this binary string back to plain text, we find the challenge answer: LOOKS_LIKE_BINARY_TO_ME.

All of this can be done using CyberChef by using the following steps.
