Thank you guys for the replies! Here's the program I made based on your and other people's advice:
void loop()
{
//7th sequence
/*i put the lcd.creatChar here in loop,
drew the sequence, then cleared the screen to avoid
repetition due to the 8 custom character limit*/
lcd.createChar(0, AmongUs);
lcd.createChar(1, heart);
lcd.createChar(2, smiley);
lcd.createChar(3, man);
lcd.createChar(4, creature);
lcd.createChar(5, house);
lcd.setCursor(0,0);
lcd.write(byte(0));
lcd.setCursor(8,0);
lcd.write(byte(1));
lcd.setCursor(15,0);
lcd.write(byte(2));
lcd.setCursor(0,1);
lcd.write(byte(3));
lcd.setCursor(8,1);
lcd.write(byte(4));
lcd.setCursor(15,1);
lcd.write(byte(5));
delay(400);
lcd.clear();
//8th sequence
lcd.createChar(0, tongue);
lcd.createChar(1, bell);
lcd.createChar(2, music);
lcd.createChar(3, down);
lcd.createChar(4, LED);
lcd.createChar(5, turtle);
lcd.setCursor(0,0);
lcd.write(byte(0));
lcd.setCursor(8,0);
lcd.write(byte(1));
lcd.setCursor(15,0);
lcd.write(byte(2));
lcd.setCursor(0,1);
lcd.write(byte(3));
lcd.setCursor(8,1);
lcd.write(byte(4));
lcd.setCursor(15,1);
lcd.write(byte(5));
delay(400);
lcd.clear();
}
