According to some "Dragon Ball Super" Episode 87 spoilers, Goku will still continue fighting Android 17 in his bid to get the artificial human to join his team. But this upcoming episode will also introduce new characters. They will steal the animals from an animal park in No. 17's territory. Apparently, the Saiyan will team up with No. 17 in preventing these animal poachers from committing their crime.
This Might Convince Android 17
Some spoilers of "Dragon Ball Super" Episode 87 suggest that this is just a filler episode. It does not affect in a significant way on what will happen in the upcoming competition. However, some fans believe that Goku helping Android 17 prevent the pirate poachers from stealing the animals may convince him to join the Saiyan's team.
"Dragon Ball Super" Episode 87 spoilers reveal that these animal poachers are pirates that are roaming around the universes to steal their animals. Perhaps they are doing these to sell those animals to other universes with few or no animals in them. At any rate, Android 17 is also working as an animal or environmental ranger in the park and it is his sworn duty to protect this area.
These Pirates Will Make A Mistake Of Underestimating Goku And Android 17
These pirate poachers arrived in a huge ship while Goku and Android 17 are fighting. They will belittle the Saiyan and the artificial human. The animal poachers don't know that the two possess awesome powers. Some spoilers of "Dragon Ball Super" Episode 87 indicate that these pirate poachers will be badly beaten by the Saiyan and the non-human.
This could mean that these pirate poachers will not be able to steal the animals from the park that Android 17 protects. Perhaps, they will leave Goku and the artificial human without a single animal in tow. No. 17 could not have done it without Goku's help. That's why there are "Dragon Ball Super" Episode 87 spoilers suggesting that No. 17 will accept the Saiyan's invitation to join the team that will protect Universe 7 in the impending Tournament of Power.
