Creep from the Deep has Billy Deep swimming to the island shore with a busted knee, whacking a zombie pirate in the ribcage with his cane, fending off a snake, and finally taking down the pirate captain. Turns out the cane he was carrying was actually the captain's leg, and he wants it back. Billy's response? He utilizes the spear fishing lessons his uncle taught him earlier, and sends the leg flying into the bastard's chest.
The second halves of every Goosebumps HorrorLand edition have an extra story in HorrorLand, slowly leading up to a crossover between the villains and characters. This is the first time that R.L. Stine has ever done something like that, excluding cameo appearances in Series 2000's Return to HorrorLand.
