Chilldrake's appearance is similar to Snowdrake's, and as the latter's name implies, Chilldrake is a drake with a snowflake-like design. Its face is arranged to resemble a snowflake with feathers sticking out symmetrically in certain locations.
Chilldrake's feathers are light green. Its beak, eyes, underbelly, and feet are all yellow. Chilldrake wears black shades, associating itself with a "chill" or "cool" fashion style.
Chilldrake's personality is the classic rebellious stereotype. Chilldrake casts anarchy wherever it goes, defies homework, refuses requests, orders, and instructions, and is willing to get into fights while supporting the idea of death during them. Chilldrake is also a contrarian, going against what is accepted for the sake of anarchy, so when the protagonist agrees with Chilldrake's contrary practices, it feels neutered and disarmed.
Despite these traits, Chilldrake has been looking for Snowdrake in Snowdin Forest ever since Snowdrake ran away from home, proving that Chilldrake cares dearly for Snowdrake and its other friends.
It uses attacks that are similar to Snowdrake's.
To spare it, the protagonist has to agree with it after performing a neutral action (similar to how Snowdrake's works), which causes it to feel less like a rebel and get uncomfortable.

- Chilldrake's name is based on Snowdrake's, switching the word snow for the word chill. This switch serves as a double-entendre; the word chill can mean "cold" as well as "easygoing," which describes both Chilldrake and his personality.
- Chilldrake does not appear in the True Pacifist Ending Credits, as killing Snowdrake is the only way to encounter it in battle.
- There is a common glitch in which, when encountered with Ice Cap and Jerry, the text reads, "Icecap and Snowdrake confront you, sighing. Jerry". This is probably due to Chilldrake being mechanically-identical to Snowdrake.
