Hearthside is an Intermediate Track in Bloons Tower Defense 5 Mobile, released in December 13th, 2018 as part of the 2018 Christmas update. In BTD5 Flash, it was released several days later, on or around December 21st, 2018.
This track takes place around the fireplace, hence its name, Hearthside. Bloons will enter from leaving the fireplace and attempt to exit by heading out the door. There is a fish tank where water towers can be placed. Multiple Christmas presents and a Christmas tree blocks placement of towers around those areas. This track has multiple sharp corners, making it useful for Tack Shooters.
