The "All monsters you control gain 200 ATK and DEF for each Hi-Five the Sky Counter on this card." effect does not start a Chain Link.
The "Once per turn: You can remove 2 Hi-Five the Sky Counters from this card; Special Summon 1 "Zubaba", "Gagaga", "Gogogo", or "Dododo" monster from your Deck." effect starts a Chain Link. (Removing 2 Hi-Five the Sky Counters from this card is a cost to activate this effect. This effect can only be activated during your Main Phase.)
