Encounter: hybrid moose/bronze dragon; like both its parent-creatures, is unlikely to be an aggressor, but is incredibly dangerous if provoked. Has a hoard of hockey memorabilia.

Hopefully the creation of that insane wizard from the old Owlbear description and not the actual product of a dragon-moose hookup.

Item: crustaceacycle, works on land and underwater equally. Must be fed once a day; will accept nearly any non-bone animal or non-woody plant matter, and so if not presented with food, carrion, or vegetation, may start nibbling on leather armor or even unattended familiars.

Can attack with its claws, as a Giant Crab: Melee Weapon Attack: +3 to hit, reach 5 ft., one target. Hit: 4 (1d6 + 1) bludgeoning damage, and the target is Grappled (escape DC 11). The crab has two claws, each of which can grapple only one target.

Item: Blazer of Shellfish Summoning. Summoned creatures are yours to command, although they are limited to their standard skills, i.e. the blue crabs might irritate an enemy by pinching it but those scallops aren’t going to do you much good unless you need to filter some water or something, unless you just want to eat them.

Encounter: Skull-Eater, a small squirrel whose diet consists entirely of human(oid) skulls, using its large incisors to inflict a powerful bite that can reach through the chinks in armor. Although it has only one HP, its high evasion makes it hard to hit, its high Defense and Magic Defense
can reduce the damage of many weaker weapons and spells to 0, and its
attacks can easily kill a party member. When hit by magic, five copies
of it will appear.
