Let's Start Over is the 8th and final level of the Teacher! It's Spring.
The level starts with Snaches and Mooths charging at the base. After some time, 4 Shy Boys will also come to the base. Owlbrows will spawn continuously from now. When the enemy base is hit, Teacher Bun Bun, Teacher A, Teacher Bear and Doge Dark will spawn.
This level is made hard for two reasons, the rush of Shy Boys at the start and the heavily buffed Bun Bun. Anti-floating units such as Strike Unit R.E.I and Delinquent Cat will make the level much easier. Anti-Red Cats may help if you are struggling at the beginning.
- This level was replaced with a weaker copy of Love and Death in early April 2016. It is currently unknown if it was an April fools or a bug. The event was then removed. It was fixed and re-released the later on in the month with the release of version 5.0.
