Pearl, like all parrots, has a love affair with going up.
Since he has a permanent left wing injury from when his siblings bullied him as a chick, as an adult he has learned to rely on his Mommy for (frequent) relocation services.
Luckily, Pearl’s Granddad has mad engineering skills. This has resulted in a system of ladders to help Pearl relocate himself unaided while Mom is attempting to write and earn rent money.
For obvious reasons, it didn’t take Pearl long to get the hang of his new system. The system basically consists of a series of interlocking ladders. The ladders take him up…..and down…..and up…..and down…..as often and as quickly as he chooses.
