Noel struggles to get a coconut open. This is probably her first time getting a coconut and she tried several methods to puncture or bust it. Coconuts are a great enrichment item since it keeps the chimps busy and engages their mind. They will often watch and learn from each other. When one of their groupmates manages to open the coconut, there will usually be lots of happy shouting, and then the others will try the same methods on their own.
