Help finding a specific toy 😫😫

I went to a mother a toddler group today and my 14 mo son was OBSESSED by this one toy.

It's similar to the one in the picture but there was fewer and bigger blocks, one that he particularly liked was kind of like to wheel in the above picture but it moved by itself (perhaps battery powered??) and much bigger

It was farm themed and you could put different farm animal heads onto the blocks.

Stupidly I didn't look at the make before I left so I've been heavy googling for the past hour trying to find it but nothing.

I'll go out the shops tomorrow to try and find something but if anyone has any idea what I'm talking about it would be a great help 😂
