Kappatoo (1990). S01 E03 = "TIME SLIME AND TISWAS" [review]

"Kappatoo adapts the phone line and Simon's computer so that he can talk to his computer in his time to find out what is wrong with his wrist band. The computer advises Kappatoo that it just needs some more fuel to operate, the only problem is that the fuel it uses is not available in Simon’s time nor will it be for the next 200 years, but by using Simon's washing machine and their next-door neighbour's satellite dish, some more fuel can be received. Kappatoo does this and now has regained the use of his wrist band, he also confesses to Steve, Simon's best friend, after a little time, and, seeing Kappatoo beam out of Simon's kitchen, Steve comes to realise the truth. Kappatoo, on the other hand, does not do well in the local football match against another school, which Simon watches from the future very unhappily.

Simon does do really well in The Hypergrid contest though, and beats Sigmasix, to everybody’s surprise and delight. Sigmasix, on the other hand, does not accept defeat graciously and beams into Kappatoo’s dome and accuses what he believes is Kappatoo of cheating." - from Wikipedia but edited by BV.
