You can use Fisher Price Baby Cubes together with Clipo. However, it is not possible to combine the cubes straight, but it is possible at an angle of 45 degrees. The blue and yellow platforms at the bottom are also Fisher-Price. These cubes have even more building possibilities that normal Peek-A-Blocks.
Robin the Bobbin, the big-bellied Ben,
He eat more meat than fourscore men;
He eat a cow, he eat a calf,
He eat a butcher and a half;
He eat a church, he eat a steeple,
He eat the priest and all the people!
A cow and a calf,
An ox and a half,
A church and a steeple,
And all the good people,
And yet he complain’d that his stomach wasn’t full.
Peek-A-Blocks are baby cubes for kids by Fisher Price brand. A side of the cube is 2 inches. Our middle daughter got these cubes first at a respectable age of 2 years old. We bought her cubes with different sounds – rattles, bells and other noisemakers. And then we got other options. There are cubes of different themes – animals, vehicles, the alphabet. Cubes are usually transparent, for example, you can see insides of cube with an animal from 5 sides.
