  For $b\leq -2$ and $e \geq 2$, let $S_{e,b}:\mathbb{Z}\to\mathbb{Z}_{\geq 0}$
be the function taking an integer to the sum of the $e$-powers of the digits of
its base $b$ expansion. An integer $a$ is a $b$-happy number if there exists
$k\in\mathbb{Z}^+$ such that $S_{2,b}^k(a) = 1$. We prove that an integer is
$-2$-happy if and only if it is congruent to 1 modulo 3 and that it is
$-3$-happy if and only if it is odd. Defining a $d$-sequence to be an
arithmetic sequence with constant difference $d$ and setting $d = \gcd(2,b -
1)$, we prove that if $b \leq -3$ odd or $b \in \{-4,-6,-8,-10\}$, there exist
arbitrarily long finite sequences of $d$-consecutive $b$-happy numbers.
