loquat, spoon
枇 centers on the loquat fruit and tree, and by extension a spoon, likely from the shape of the loquat leaf or the use of its wood.
枇 combines 木 (tree) with 比, which likely contributes the sound. The character originally referred to the loquat tree and its fruit.
The tree radical 木 beside 比, which looks like two people sitting side by side, can be remembered as two people sharing loquats under a tree. The spoon meaning comes from the shape of the loquat leaf, often used as a makeshift spoon.
For ビ, imagine a bee buzzing around a loquat tree: bee -> ビ, and the bee lands on a loquat-shaped spoon.
