You really can make a food puzzle out of just about anything!
These objects can increase or decrease in difficulty depending on how many holes you make and how full you fill the toy.
When there are only a few pieces left it can be challenging whereas a full toy is much easier.
This is an odd and unique shape which adds some nice variety to what hopefully becomes a large collection of foraging toys. Remember it is important to offer many different puzzles for the benefit of mental enrichment!
