Hey, does anyone know the name of an old animated film about a little blond boy in space? All I can remember is there was a space funeral scene towards the end where someone ( i think the captain of the big space ship) dies and his coffin was launched into space and as the coffin drifts away there is sad music playing that has scarred me when I was younger. There were also different scenes of the boy going to different planets that had weird creatures and plants. He gets lost I think and I remember a specific planet had a pink/red hue and had holes with weird spooky tentacled creatures in them. The plot was sad I think and it had the vibe of a  ghibli movie. It was a long time ago that i watched this so sorry for the lack of important detail.
