Right before Aladdin wishes Genie free, just like he does in the original, Genie proposes some new princely identities for Aladdin to wish for. One of them is a bow and arrow sporting charmer that looks a lot like Robin Hood, a story which Disney made into an animated feature starring a fox in 1973.
Also, Jafar's hypnotizing snake staff, which is a staple from the '92 film as well, resembles the Robin Hood character Sir Hiss, who uses his eyes to hypnotize other characters. Sir Hiss, in turn, is a reuse of Kaa, the hypnotizing snake from 1967's The Jungle Book.
In fact, Disney reused a lot of animation in its earlier films, which might explain the studio's love of hiding Easter eggs now. But instead of reusing animated sequences, the more recent films, both live-action and animated, have found a fun way to pay homage to the movies that came before.
