Sting (Middle-earth)
Sting has the magical ability to detect orcs or goblins nearby, glowing blue in their presence, as it did when the Fellowship encountered orcs in the mines of Moria. Tolkien establishes this as a common property of First Age Elf blades, particularly those forged in Gondolin. Sting is also exceptionally sharp. Bilbo manages to thrust it without effort deep into a wooden beam at Rivendell. Frodo also wounds a troll in Moria, after Boromir notches his own sword with his attempt. Sam uses Sting to cut through the giant spider Shelob's strong webs with ease, and also wound the spider, driving it away from the paralyzed Frodo.
Tigger
Tigger is introduced in Chapter II of "House at Pooh Corner", when he arrives at Winnie-the-Pooh's doorstep in the middle of the night, announcing himself with a stylised roar. Most of the rest of that chapter is taken up with the characters' search for a food that Tigger can eat for breakfast — despite Tigger's claims to like "everything," it is quickly proven he does not like honey, acorns, thistles, or most of the contents of Kanga's larder. In a happy coincidence, however, he discovers what Tiggers "really" like best is extract of malt, which Kanga has on hand because she gives it to her baby, Roo, as "strengthening medicine".
