Bigfoot is a BB(3,3) Cryptid. It simulates the Collatz-like function

$\begin{array}{l} A (a, & 6 k, & c) & \to & A (a, & 8 k + c - 1, & 2) & if & 8 k + c \geq 1 \\ A (a, & 6 k + 1, & c) & \to & A (a + 1, & 8 k + c - 1, & 3) & if & 8 k + c \geq 1 \\ A (a, & 6 k + 2, & c) & \to & A (a - 1, & 8 k + c + 3, & 2) & if & a \geq 1 \\ A (a, & 6 k + 3, & c) & \to & A (a, & 8 k + c + 1, & 5) \\ A (a, & 6 k + 4, & c) & \to & A (a + 1, & 8 k + c + 3, & 2) \\ A (a, & 6 k + 5, & c) & \to & A (a, & 8 k + c + 5, & 3) \end{array}$

$A (0, 6 k + 2, c) \to Halt (16 k + 2 c + 7)$

starting from $A (2, 1, 2)$ .
