This bird is extremely heavy, so he won't fly very far, but his weight can be decreased by tapping the srceen
The actual weight is unknown
This bird can crash through 32 wood blocks, 16 ice blocks, 8 stone blocks and 4 columns. After tapping the screen, each of these gets divided by two up to a maximum of 5 times, where he loses his ability to crash through columns, stone and ice but retains his ability to crash through 1 wood block, making him the lighter Red Bird. Add more blocks, I only know of these.
Its special ability can be used a maximum of five times, each time decreasing his size, weight and durability.
