I remember seeing this short cartoon as a child but everyone thinks I'm crazy when I explain it... its about a little girl with bopped brown hair who visits her grandfather. They plant seeds together eat ice lollies then build sand castles on the beach together. One day she arrives and checks their usual haunts (the beach etc) but cannot find her grandfather. She sees his chair empty with his slippers cane and pipe lying and it turns out he's died. It sounds really sad and kind of traumatised me lol can anyone help me find the name of it? Its quite old.

I believe its called Granpa. You can find it on Youtube
