Baby Shower & Nursery Theme

What is some creative themes for both baby shower and nursery for a boy .. I was thinking the lion king . I wanted to classic yet different . A lot of people seem to be into all the new characters that’s out . Any pictures? I can’t go all out with paint because I live in an apartment. And does anybody know where you can get the sticky wall decal that covers the side of you wall ( I hope you know what I’m talking about ) since I can’t paint
