Chocolate Wall Doge is a variant of Wall Doge that looks like a bar of chocolate, fitting for the Valentines Event it is featured in. While it has low range and single target damage, it has Mini-Waves, which allow it to deal steady, constant damage, especially when stacked.
Due to its large health pool, it can take quite the beating before dying. Also note that it cannot be permanently frozen with Bombercat due to its freeze immunity, leaving it to be a constant danger as long as it is left alive.
In level 14 of Chocolate Wall Doge's Gauntlet, Chocolate Wall Doge was accidentally buffed to 3,560% instead of the intended 660%. This was patched in BCJP 10.3. However, BCEN 10.2 had this bugged level for longer than BCJP.
