How to get: To unlock Cai Shen: play as Fortune Chicken or Xi. You need to pick up the red envelopes scattered along the ground.
You’ll need to collect a total of 21 red envelopes to unlock Cai Shen.
However, unlike most other requirements, these envelopes are cumulative
and can be collected over multiple runs: if you play five times and
collect five envelopes each time, you’ll unlock him after the fifth run.
Traits: Cai Shen runs in the same world as Fortune
Chicken and shouts things in Chinese as he runs. Fun fact: Cai Shen is
the Chinese god of wealth and the red envelopes you use to collect him
are traditionally used to present monetary gifts.
