Garden: Tank Trap
More rock & roll in large.
Quiet day at home...
Tank makes sitting in the garden in the summer rather perilous: he relentless pursues and attacks feet. If something is vaguely tortoise-sized and moves on the ground, it is for attacking, and he never gives up, like a monstrous little automaton. He doesn't attack fingers or hands (you can stroke his chin or hand feed him safely), but feet/shoes are never safe.
His attack strategy is straightforward (literally): he proceeds directly towards the challenge and rams, head-butts, and bites. This tennis ball had appeared on the lawn (presumably knocked over a neighbouring fence): by standing the other side of it from him, he'd run into it (obliviously: he didn't seem to see or register it) and continue his direct attack approach, clambering awkwardly over the ball. Silly creature!
