I found a sneak peek on YouTube and I found out that 11 special characters will be available on Monday. There will be other add-ons too such as the hoverboard and the jetpack. Here is the list below:

Akira

Boombot

Ella

Frank

Fresh

Jake

Jake Chicken

Skye

Tagbot

Tricky

Yutani

Now, I wonder why Crossy Road decided to add only a few characters and why they chose these specific characters.
