Lemonhope

Lemonhope (real name Badlemonnohope) is a small and young Lemon Child who was imprisoned by the tyrannical Earl of Lemongrab for playing the harp, even though he has great talent. Finn and Princess Bubblegum attempt to rescue him but are imprisoned in a dungeon. Lemonhope tries to play Finn's flute while imprisoned, but he does it poorly. However, the music he plays are attractive to the Lemongrabs, which causes the browbeaten Lemongrab 2 to free him, earning the wrath of his original counterpart. Finn, Princess Bubblegum and Lemonhope escape Castle Lemongrab with the help of Lemongrab 2 and the other Lemon Children, who see Lemonope as the hope of their people. He is taken to the Candy Kingdom where he can attend school.
