So I barley remember this cartoon but I've been trying to remmebr it from years

Its animated very old maybe is the 90's or before
I remmber they are two charecters who lived in a house made from wood in a forest.. I remmber an episod where a lady goes to them and they dance
And she eats all the strawberry jam

The charectors are boys they had very thin legs

It isn't colourful or the usual cartoon the drawing was very blue gray type
And the characters didn't talk much

I know it isn't a lot but please help !
