Since COC has underwent many themes, such as Christmas and Halloween, and has numerous background during raid, such as the volcano and lava background during war, I hope that players may choose such background/theme 24/7 outside of the actual season. By allowing players to add more visual effects to their villages, attacker might get new kinds of excitement when going through the clouds and checking enemy bases to raid. It also provide additional visual effects for better gameplay. For example, I might be going through the cloud and find some villages with volcanic, snows, or night theme backgrounds/themes.
