Orange Triangle

The Orange Triangle, also commonly known as Burnt Triangle or Sunburnt Triangle, is a shape that can very rarely evolve from Triangle or Green Triangle, and gives a lot of experience upon destruction.

History
Orange shapes and Orange Triangle in particular were added secretly, without any reference in changelogs. Supposedly they were added during summer of 2019. On 6 May 2021, they were given the Torch ability and aura.

Design
Orange triangles are slightly larger in size than normal triangles, and have an orange color and aura.

Technical
Orange Triangles have 20 health and give about 22000 experience upon death. They are very rare, and can evolve into Orange Pentagons, but they usually stay as Orange Triangles. They have the Torch ability.

Strategy
Orange Triangles give a lot of experience, and as such extremely useful to low-tier tank. If you spawned near Orange Triangle, you should gain a bit higher level and try to destroy it for experience. This way, you will be able to level up very fast. You may consider yourself lucky if you find this shape, as it is pretty scarce. When infected, Orange Triangles are much slower and more durable than Triangles.
