It would have made more sense for Dark Yellow to have been an original part of
this set. This 2x2 brick may have also appeared in 4683. That is harder to prove
given the lack of available photos but the IDs for half of the parts that appeared
in that set are very close, including the 2x2 Dark Yellow brick:
3437 Dark Yellow: 4216272
4882 Medium Blue: 4216273
